| Abstract: | Potassium alkyl xanthates with varying carbon chain length were synthesized and purified.The purities of synthesized samples were determined by the ultraviolet-visible spectrophotometric(UV-Vis) measurement and were found out to be over 99%.Zinc sulfide and cadmium sulfide nanoparticles were successfully synthesized by a unique precipitate dissolution method using metal alky xanthate precipitate and sodium sulfide as a metal and a sulfur source respectively.The synthesized samples were characterized by low ... |
