摘要： 利用金橙-2分光光度法研究了饱和KCl溶液中十八胺盐酸盐浓度的测定方法,考察了缓冲溶液用量、显色剂用量和稳定时间等因素对测定的影响,确定了测定的优化条件。结果表明,十八胺盐酸盐-金橙-2络合物的最大吸收波长为485 nm,标准曲线线性良好,回归方程为y=0.063 7x-0.068 9,相关系数R2=0.991 3,测定结果的相对标准偏差为1.53%。该法重现性好,准确性较高且操作简便,可应用于KCl浮选的饱和KCl溶液中十八胺盐酸盐的测定。

Abstract: Determination of content of octadecylamine hydrochloride in KCl saturated solution with orange Ⅱ spectrophotometric method was studied.Factors that affecting the test results such as the amount of buffer solution and indicator,and the time for stabilizing the chromogenic reaction were investigated;and the optimized experimental conditions were identified.Results indicated that the maximum absorption wavelength of the complex formed by octadecylamine hydrochloride and orange Ⅱ is 485 nm that showing good linearity with regression equation of y=0.063 7x-0.068 9.The correlation coefficient is 0.991 3.The relative standard deviation of quantitative analysis method is 1.53%.

Key words: octadecylamine hydrochloride, spectrophotometric method, quantitative analysis
