✦ Synopsis

A method of simultaneous analysis of anions and transition metals in complex form is proposed. Complexes are formed in the separating sorbent under excess quantity of ligand being introduced into the system after conventional separation of sample anions. In order to realize the method, a new central localized sorbent is prepared which has low anion exchange capacity and high cation one. Conditions of separation of mixture contained F-, Cl-, NO2, HPO 2-, Br-, NO3, SO 2-, and Cd 2+, Zn 2+, and Cu 2+ are found. Detection limits and standard deviation are determined.
