A process for treating colored liquid comprises a step of contacting a colored liquid and functional water generated by electrolysis of a water solution of an electrolyte under light irradiation, to decolorize efficiently and stably to a low chromaticity.

Method for treating colored liquid and apparatus for treating colored liquid

A method for decomposing halogenated aliphatic hydrocarbon compounds or aromatic compounds characterized by contacting the compound to be decomposed with functional water under light irradiation, wherein the functional water is characterized by a hydrogen ion concentration (pH) of 1-4, an oxidation-reduction potential of 800-1500 mV (working electrode: platinum, reference electrode: silver-silver chloride) and a chlorine concentration of 5-150 mg/l, and the irradiation is carried out with light of a wavelength of 300 nm or more, with an intensity of 10 mW/cm or less. This method is carried out at room temperature under the atmospheric pressure. An apparatus for the method is also provided.

A surface plasmon resonance sensor apparatus includes a common substrate, a surface emitting laser, such as a VCSEL, arranged on the common substrate, a sensor array, such as CCD array, arranged on the common substrate, a light-transmitting medium provided above the common substrate, and a metal thin film formed on the light-transmitting medium to cause surface plasmon resonance due to light which is emitted from the surface emitting laser, transmitted through the light-transmitting medium and impinging on the metal thin film. The surface emitting laser, metal thin film and sensor array are positioned such that a change in an intensity of light reflected by the metal thin film caused by the surface plasmon resonance can be measured by the sensor array.

Surface plasmon resonance sensor apparatus using surface emitting laser

An apparatus for soil remediation to remedy a soil contaminated with a pollutant less affecting the environment, which includes a soil borer having a rotatable drilling form or portion capable of agitating the soil, introducing into the soil at least one agent selected from the group consisting of a microorganism capable of degrading the pollutant, a nutrient for the microorganism and an inducer to make the microorganism express the pollutant-degrading activity, and measuring pollutant concentration in the soil.

Apparatus for soil purification and remediation method for contaminated soil

A bacterium strain JM1 (FERM BP-5352) capable of degrading organic compounds without inducers is disclosed. Further, methods for degrading organic compounds and remedying an environment using the bacterium strain are also disclosed. The microorganism is brought into contact with the environment under conditions which stimulates the organism to degrade the organic compounds and thus, remedying the environment of pollutants. A kit and method for selectively detecting the strain expressing oxygenase from a sample containing strain J1 FERM BP-5102 is also disclosed. The latter strain expresses oxygenase when induced, however, strain JM1 FERM BP-5352 does not require induction. In addition, a process for obtaining strain JM1 FERM BP-5352 is also disclosed.

A method for remedying an environment containing a pollutant using microorganisms comprising a step of injecting a liquid containing a microorganism which can decompose the pollutant into a predetermined site of the environment to be remedied, wherein a gas has been dissolved into or mixed with the liquid by applying a pressure higher than the pressure at the injection site and the liquid evolves the gas when injected into the predetermined site, and an apparatus which comprises a means for injecting a liquid containing a microorganism which can decompose a pollutant into a predetermined site of the environment, wherein the means injects the liquid in which a gas has been dissolved into or mixed with by applying a pressure higher than the pressure at the injection site, into the environment under a pressure so that the gas does not evolve from the liquid before injection.

Method and apparatus for remediation of contaminated soil

A method and apparatus for diffusing a treating agent into a medium, a method and apparatus for injecting a liquid into a medium, and a method of remedying soil. The method of diffusing a treating agent into a medium, comprises a step in which a solidified treating agent is scattered and diffused by the pressure of a gas resulting from a gas-generating agent.

Method for dispersing chemicals and microorganisms into soil using

An apparatus for degrading a pollutant to purify a medium containing a pollutant using a microorganism, which comprises a container in which a region containing a microorganism capable of degrading the pollutant is provided, wherein the container has the first opening for introducing the medium into the container and the second opening for draining the medium passed through the region containing the microorganism from the container, and in the container a region containing a functional material which releases a material required for degrading the pollutant by the microorganism is provided between the first opening and the region containing microorganism.

Apparatus for degrading pollutant, process for purifying contaminated

A process for remedying polluted soil which comprises the steps of injecting a liquid agent containing a microorganism into the polluted soil, and injecting a gas into a region wherein the water content of the soil became 0.6 or more times its saturation water content after the injection of the liquid agent. Using this method bioremediation of contaminated soil can be economically and efficiently carried out.

Process for remediating soil

Provided is a fluorometric analytical method for detecting chloride ion in a sample by quenching of fluorescence of a fluorescent dye, the fluorescent dye being one of 3,6-bis(dimethylamino)acridine and a derivative thereof of the formulae ##STR1## wherein R is alkyl having 1 to 30 carbon atoms, and X.sup.- is a halogen ion.

Fluorometric analysis of chloride ion and chemical sensor therefor

A process for microbial remediation of soil polluted with a pollutant by introducing into the polluted soil a decomposing microorganism, a nutrient and/or an inducer necessary for the expression of a decomposing activity in the microorganism, wherein a coefficient of permeability of the polluted soil is controlled to be small and uniform so that the introduced substance may be uniformly distributed over a soil area to be remedied. Also a process for treating soil which comprises a step of controlling the coefficient of permeability of the soil so that a peak at the substantially smallest coefficient of permeability may comprise the largest percentage in the distribution of coefficient of permeability.
