In order to create highly sensitive electrodes that detect a number of drugs during operation Ion selective electrodes (ISEs) were prepared based on membranes containing heteropolymetallophosphate ionophores. A total of 12 drugs widely used in medical practice were selected for the preparation of...

The article shows the possibility of using sodium 4-amino-5-hydroxy-3 - ((e) - (4-nitrophenyl) diazenyl) - 6 - ((e) -phenyldiazenyl) naphthalene2,7-isulfonate, immobilized on polyacrylonitrile fiber PPD, as a reagent for the determination of lead ions. The optimal conditions for immobilization and...
