Green approaches to colorimetric monitoring of calcium in water
Abstract:
Simple, ecologically harmless chemical reactions have always been a point of interest for chemists and analysts as fit to be applied to work in or out of laboratories. A new concept of chemical analysis is exemplified in the article by means of selective determination of calcium ions with the organic reagent arsenazo III (2,2'-[1,8-dihydroxy-3,6-disulfonaphthylene-2,7-bisazo]-bisbenzenearsonic acid disodium salt) with no application of toxic solvents during the seasonal analysis of water in the Yauza River (the city of Moscow).
