A biodegradable starch film is provided. The biodegradable starch film includes a starch which is cross-linked by means of a cross-linking agent. The cross-linking agent comprises glycidyl methacrylate (GMA), octenyl succinic anhydride (OSA), or dodecyl succinic anhydride (DDSA) or combinations thereof. The cross-linking agent is 1 to 10 weight parts based on the starch of 100 weight parts. Furthermore, a method for manufacturing starch foam is also provided.

Starch film and method for manufacturing starch foam

The present invention provides a process and apparatus for treating contaminated gas. A contaminated gas containing volatile organic compounds is continuously introduced into a reactor to allow the gas to contact a metal oxide catalyst and an oxidant for a period of time. The concentration of the volatile organic compounds can be thus reduced. The treated gas is then continuously emitted from the reactor. The concentration of the organic compounds of the emitted gas and/or the concentration of the oxidant are continuously monitored, and the oxidant feeding amount is controlled according to the monitored concentration. By means of the process of the present invention, volatile organic compound-containing waste gas with high humidity can be effectively treated, and the utility rate of the oxidant can be increased.

Process and apparatus for treating contaminated gas

A method and apparatus for treating an exhaust gas containing volatile organic compounds. The method includes the steps of: introducing an exhaust gas into a wet scrubber, so that the organic pollutants in the exhaust gas are absorbed by a scrubbing water; pumping the scrubbing water containing the organic pollutants into at least one oxidation tank, thereby causing oxidation reaction between the organic pollutants and an oxidizing agents containing ozone; and introducing the scrubbing water after the oxidation reaction into the wet scrubber. The oxidizing agent further comprises hydrogen peroxide.

A method for automatically detecting waste gas. The waste gas is led into a multiple switching valve through which the waste gas is sampled. Then, the waste gas sample is conveyed to an empty column and/or a chromatographic column, via the multiple switching valve. Then, the total hydrocarbon content of the waste gas sample is measured when the waste gas sample is conveyed to the empty column, and the waste gas sample is separated for measuring individual volatile organic compound concentrations of the waste gas sample when the waste as sample is conveyed to the chromatographic column.
