Patent number: 4652396Abstract: There is disclosed a method for increasing the electrical conductivity of a porous synthetic polymeric material. The method comprises depositing an effective amount of a polyacetylene polymerization catalyst throughout the porous structure, subsequently exposing said material to acetylene under polymerization conditions, for a time sufficient to form polyacetylene within the porous structure, and finally doping the resultant product with a conductivity modifying amount of either an electron donor dopant or an electron acceptor dopant.There is also disclosed an improved electrodialysis process wherein an electrolyte solution is placed between opposite faces of two membranes, the first membrane being an anion exchange membrane and the second membrane being a cation exchange membrane, while being subjected to a primary electric field causing the cations in the electrolyte to pass through the cation exchange membrane and the anions to pass through the anion exchange membrane.Type: GrantFiled: May 6, 1983Date of Patent: March 24, 1987Assignee: Akzona IncorporatedInventor: Kenneth B.

Patent number: 4650587Abstract: A new and useful particulate magnesium phosphate product (MGP) and method of use therefor are disclosed for removing ammonia from aqueous solutions, e.g., recirculating dialysate solutions and intragastrointestinal fluids as may result from the hydrolysis of urea. This particulate magnesium phosphate product (MGP) acts as a remarkably effective scavenger wherein under equilibrium conditions only about six (6) grams of the novel product are required to bind the ammonia (more exactly, ammonium ions) liberated from one (1) gram of the urea, a result far superior to traditional zirconium phosphate (ZP) prior art materials which under ideal conditions require about 17-20 grams of ZP per gram of urea. The novel particulate magnesium phosphate product can be exploited in one embodiment as a replacement for the older ZP materials used to remove ammonia produced by enzymatic hydrolysis of urea in recirculating dialysis systems utilizing disposable cartridges.Type: GrantFiled: September 9, 1982Date of Patent: March 17, 1987Assignee: Akzona IncorporatedInventors: Robert B.
