比值导数光谱-多波长最小二乘回归分光光度法同时测定磷、硅、砷
Simultaneous Determination of P,Si and As by Absorption Ratio Derivative and Multiwave-Length Linear Regression Spectrophotometry Combined with Least Absolute Deviation Method
【摘要】 应用吸光度比值导数与多波长最小二乘回归分光光度法测定了 P、Si和 As 3组分混合物。合成试样6次平行测定的 RSD为 0 .12 %— 3.76 %。回收率在 90 .0 %— 10 8.9%之间
【Abstract】 The determination of ternary mixture of P,Si and As by ratio absorption derivative was studied.The relative standard deviation of six determinations is 0.12%-3.76% for forming samples.The recovery of this method is about in the range of 90.0%-108.9%
