Аннотация We have started systematical research of extraction and complexing properties of wide range of ligands based on aromatic and heteroaromatic rows and amino acid derivatives. Pre-experiment showed us that compounds 1aa and 1bc have good solubility in metiltrialkilammonium (MTAA) carbonate in toluene, and 1ba and 1bb compounds have a low lipophily. Cesium extraction by compounds 1aa, 1bc, 1ba and 1bb in mixture with MTAA carbonate in toluene from carbonate media was studied by method of isomolecular series. It was found out, that compounds 1ba and 1bb in mixture with MTAA carbonate in toluene have better cesium extraction properties from carbonate media then compounds 1aa and 1bc, and optimal conditions for carrying out cesium extraction by amino acid derivatives in mixture with MTAA carbonate in toluene from carbonate media was found. Stoichiometric of the extracted complexes and the isotherm of extraction of cesium by amino acid derivatives in mixture with MTAA carbonate in toluene from carbonate media were obtained.
