Abstract
The polycarboxylic amino acids were examined as possible retarding agents in the precipitation of calcium oxalate. The effect was observed by continuous determination of the concentration of Ca2+ in a mimic urine solution. Both polyglutamic and polyaspartic acids, when used in 5-100 ppm concentrations, significantly retarded calcium oxalate precipitation.
