Time depended inhibition of SPMs Na+ /K+ -ATPase induced by cadmium and lead

In this work, time depended interaction of SPMs Na+ /K+ -ATPase with Cd2+ and Pb2+ by single exposure and in the mixture, was investigated. The possibility to selectively detect these ions on the basis on the rate of their interaction with the protein was studied. The decreasing protein concentration increased the sensibility of Na+ /K+ - ATPase towards both metals. The selectivity was obtained by variation of metalenzyme contact time.Physical chemistry 2004 : 7th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 21-23 September 200
