【Abstract】 Aspectrophotometric method for the si-multaneous determination of nickek, iron andcobalt in a sample solution based on the dif-ferences in absorption spectra of this com-plexes with nitrite-R in acetic acid buffer so-lution. The interferences among the ele-ments to be determined can be effectively e-liminated by using the K-coefficient method.Satisfactory results are obtaincd by the pro-posed method.更多还原
