摘　　要：利用丁二酮肟分光光度法测定红土镍矿中的镍。研究了波长、NaOH、显色剂及氧化剂等试剂用量对吸光度的影响,得出了较佳的实验条件;同时通过加标回收验证了方法的可靠性,回收率为101.1%,相对标准偏差RSD(n=10)为0.54%。实验证明了方法准确、可靠,是一种快速测定红土镍矿中镍含量的便捷方法。In this paper, the content of nickel in Laterite-nickel Ore was det spectrophotometry. The influence of wavelength and the amounts of reagent gent and ammonium persulfate, were investigated. A better experimental cc same time, standard additions tests were performed. The results indicate tha able with the recovery of 101.1% and the relative standard deviation （RSD, od is accurate and reliable, and a convenient method for fast determination o
