本文应用阳极氧化镍与溶液中丁二肟生成难溶络含盐沉积在玻炭电极表面而富集痕量镍,然后阴极溶出测定。对富集和溶出的实验条件作了探讨,并成功地测定了天然水中ppb级的痕量镍。
In this paper, the anodic nickel oxide and the solution of butanedioxime to form insoluble solute salt deposition on the surface of glassy carbon electrode to enrich trace nickel, and then cathodic dissolution determination. The experimental conditions for enrichment and dissolution were explored and the ppb grade trace nickel in natural water was successfully measured.
