摘要

A spectrophotometry has been developed for determination of Ni content in nickel laterite ores. The sample was dissolved by mixed acids of HCl, HNOning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA" lang=EN-US>₃, HF and HCLOning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA" lang=EN-US>₄ with appropriate proportions. The experimental results indicate that this method is stable and reliable, and it can be applied to rapidly and accurately determine Ni in nickel laterite ores.
