The acid-base properties and the complexation of tributyl [aminotris(methylenephosphonic acid)] in aqueous solution

Abstract

© 2016 Taylor & Francis Group, LLC.The acid-base and complexing properties of tributyl [aminotris(methylenephosphonic acid)] (H3L) with divalent metals were investigated in aqueous solution via the potentiometric titration method. The formation of 1:1 species partially protonated [MH2L] and totally deprotonated [ML−] as well as hydroxo species [M(OH)L2−] has been established
