Abstract

Inventia se refera la o metoda de preparare a materialului electrodic activ pentru electrodul cu membrana Cd exponent 2+ selectiv, pe baza de CdS-Ag indice 2 S, prin precipitarea amestecului de azotatie de Cd exponent 2+ si Ag exponent +, la care, înscopul obtinerii unor sulfuri cristaline, se supune precipitarii un amestec de azotati cu tioacetamida corespunzator realizarii unui raport molar Cd:Ag indice 2 S de 1:1...4:1, sub agitare puternica, la temperatura de 2...5 degree C, urmata de încalzire ti mp de o ora la 70...80 degree C si de spalare prin decantari repetate cu apa bidistilata la început calda, apoi rece, dupa care se filtreaza, se spala pe filtru cu acetona si se usuca în vid la 40 degree C.The invention relates to a method of preparing the electrodically active material for the selective Cd 2+ selective membrane electrode based on the CdS-Ag index 2 S by precipitation of the Cd exponent 2+ and Ag exponent + In order to obtain crystalline sulfides, a mixture of nitrates with the thioacetamide is precipitated, corresponding to a molar ratio of Cd: Ag index 2 S of 1: 1 to 4: 1, with vigorous stirring, at a temperature of 2 ... 5 ° C C, followed by heating for one hour at 70 DEG-80 DEG C. and washing by repeated decanting with bidistilled water at first warm and then cold, then filtered, washed on the filter with acetone and dried in vacuo at 40 degrees C.
