STUDY OF IMMOBILIZATION OF BROMPIROGALLOLIC RED IN THE GELATINOUS MATRIX AND EVALUATION THE ABILITY TO CREATE ON ITS BASIS AN OPTICALLY TRANSPARENT SENSOR FOR DETERMINATION OF METALS
The regularities of sorption in the brompirogallolic red layer of gelatin gel. Set the pH range of reagent for maximum sorption of dye. Calculations show that in the gelatin layer adsorbed predominantly ion-N3Ind. Established the time to reach equilibrium sorption process, study the dependence of the degree of extraction of the dye and the adsorption capacity of gelatin in optimal conditions of sorption of phase contact time and concentration brompirogallolic red in solution. The possibility of creating transparent optical sensors based on immobilized in gelatin brompirogallolic red for the determination of heavy metals.
