Process for removing pollutants from aqueous streams

An apparatus and process for forming an array of powder samples arranged in predefined locations where all samples have a flat surface in a common plane has been developed. A monolithic block having a main support section having at least N perforations from a first surface of the main support through a second surface of the main support in predefined locations, where N is the number of samples in the array is provided. The monolithic block also has a flat support section covering the perforations of the main support section. All N samples are loaded simultaneously with sample X in perforation X of the main support where X is an integer from 1 to N. A flat surface of each sample where the flat surfaces are a common plane is formed by forcing the samples within the perforations against the flat support. The samples are retained in position within the perforations against the flat support, and are made ready for analysis since the flat surfaces of the samples are in predefined locations and are all in a common plane.

Process of parallel sample preparation

A process of forming an array of powder samples arranged in predefined locations where all samples have a flat surface in a common plane has been developed. A main support having at least N perforations from a first surface of the main support through a second surface of the main support in predefined locations, where N is the number of samples in the array is provided. The main support is equipped with a flat support temporarily attached to its first surface. All N samples are loaded simultaneously with sample X in perforation X of the main support where X is an integer from 1 to N. A flat surface of each sample where the flat surfaces are a common plane is formed by forcing the samples within the perforations against the flat support. The samples are retained in position within the perforations against the flat support, and are made ready for analysis by exposing the flat surfaces of the samples by removing the flat support. The exposed flat surfaces of the samples are in predefined locations and are all in a common plane. Alternatively, the flat support may be permanently attached to the main support.

Process and composition for removing toxins from bodily fluids

Process for removing toxins from bodily fluids using zirconium or titanium microporous compositions

A process for removing toxins from blood is disclosed. The process involves contacting the blood with a microporous ion exchanger to remove toxins in the blood. Alternatively, the blood can be contacted with a dialysis solution which is then contacted with the ion exchanger. The microporous ion exchangers are represented by the following empirical formulae:

Process for removing toxins from blood using zirconium metallate or

A new family of crystalline and microporous compositions having indium and silicon as essential framework elements have been synthesized. These compositions are characterized by unique x-ray diffraction patterns and an empirical formula of:

Family of microporous indium silicate compositions

A new family of crystalline molecular sieves have been synthesized. These compositions have a microporous structure of ZrO.sub.3 octahedral units, and at least one of SiO.sub.2 tetrahedral units and GeO.sub.2 tetrahedral units. Optionally, the molecular sieves contain M metals such as titanium, niobium, or tin. These novel molecular sieves are prepared hydrothermally from a reaction mixture composed of reactive sources of the components. Additionally, these molecular sieves are useful for the selective adsorption of ammonium ions.
