An electrochemical method for the simultaneous determination of lead(Ⅱ) and Cadmium(Ⅱ) with a calix[6]arene modified carbon paste electrode (CPE) has been dev
The Pb-birnessite was prepared by ion exchange from K-birnessite, which was synthesized by calcination of KMnO4. Measure methods of SEM (scanning electron micro
Multi-objective optimization is a new focus of evolutionary computation research. This paper puts forward a new algorithm, which can not only converge quickly,
