Abstract

"ADITIVOS DE INIBIçãO DE EVOLUçãO DE HIDROGêNIO PARA ELETROPRODUçãO DE ZINCO". Um sal de cetilpiridínio, cloreto de cetilpiridínio (CPC) é empregado como um inibidor de evolução de hidrogênio (um melhorador da eficiência da corrente) em um processo de eletroprodução de zinco comercial. As composições de eletroprodução de zinco contendo a) antimónio e b) antimónio e cola foram testadas. A adição de CPC em uma concentração de 0,05 mm ao líquido de eletroprodução resultou em eficiência da corrente aumentada para ambos os eletrólitos."HYDROGEN EVOLUTION INHIBITION ADDITIVES FOR ZINC ELECTRODUCTION". A cetylpyridinium salt, cetylpyridinium chloride (CPC) is employed as a hydrogen evolution inhibitor (a current efficiency enhancer) in a commercial zinc electroproduction process. Zinc electroproduction compositions containing a) antimony and b) antimony and glue were tested. Addition of CPC at a concentration of 0.05 mm to the electroproduction liquid resulted in increased current efficiency for both electrolytes.
