| abstract | A novel particulate magnesium phosphate (MGP) product is described and its method of use to extract ammonia from aqueous solutions, for example, recycle dialysis solutions and intra-gastrointestinal fluids that may result from hydrolysis urea. This particulate magnesium phosphate (MGP) product acts as a remarkably effective co-precipitant; under equilibrium conditions, some six (6) grams of the new product are sufficient to bind the ammonia (more precisely the ammonium ions) released from one (1) gram of urea, a result far superior to traditional phosphate materials. zirconium (ZP) of the prior art which, under ideal conditions, requires between 17 and 20 grams of ZP per gram of urea. In one embodiment, the new particulate magnesium phosphate product can be used as a replacement for the old ZP materials used to extract the ammonia produced by the enzymatic hydrolysis of urea in recycling dialysis systems using disposable cartridges. Another embodiment describes a new encapsulated product (comprising a membrane wall, insoluble in water, permeable to urea and / or ammonia and to water and impermeable to the enzyme urease, the wall surrounds a heart formed from urease and the new particulate magnesium phosphate product) which can also be used as a co-precipitant in vivo or in vivo. This particulate MGP product can also be used to extract ammonium ions either produced by enzymatic or non-enzymatic hydrolysis of urea or by proteins or amino acids, or available as NH4 + from its original source. Also described are two methods of preparing the particulate magnesium phosphate product. |
