| Abstract: | In this paper, the content of nickel in Laterite-nickel Ore was determined by dimethylglyoxime spectrophotometry. The influence of wavelength and the amounts of reagents including NaOH, color reagent and ammonium persulfate, were investigated. A better experimental condition was obtained. In the same time, standard additions tests were performed. The results indicate that the proposed method is reliable with the recovery of 101.1% and the relative standard deviation (RSD, n=10) of 0.54%. The method is accurate and reliable, and a convenient method for fast determination of nickel in laterite-nickel ore. |
