摘　　要：利用对称二苯氨基脲在酸性溶液中与六价铬的特效显色反应,用光度法测定镀镍溶液中六价铬杂质的含量,测定时,波长为530nm,用镀镍底液作参比液。试验表明,镀液中的各种组分均不影响铬的测定。本方法简单、快速而准确。The chrome(Ⅵ) content in Ni plating solution of determined by spectrophotometric method with specific reaction of sym-diphylcarbazide with chrome(Ⅵ). The Ni plating base solution was taken as reference. The experiment resultes showed that the components in Ni plating solution would give no influence on determinations.
