Monitoring Pb2+ contentin drinking water is an important measure to safeguard safety for residents. To overcome drawbacks available electrochemical sensors, this work attempts fabricate a boron-doped diamond (BDD) electrode detecting in water. A systematic investigation was conducted on microstructural and performances of BDD electrode. The results show that, grains arrange well surface. exhibi...

The kinetics of zinc and lead ions removal by modified zeolite-clinoptilolite has been investigated. The rate of the ion exchange process for lead ions is faster than for zinc ions, as well as the time needed to reach the equilibrium. The ion exchange capacity of zeolite of lead ions is doubly higher than that of zinc ions. Diffusion models according to the Vermeulen's approximation, the parabo...
