偏最小二乘-分光光度法同时测定锌铜镍
Simultaneous spectrophotometric determination of zinc, copper and nickel by partial square method
【摘要】 研究了用偏小二乘(PLS)分光光度法同时测定水体中的Zn2+、Cu2+和Ni2+的方法,并与P矩阵、K矩阵、多元线性回归进行了比较.结果表明,PLS法简便快捷,测定结果更加准确可靠.
【Abstract】 The application of partial least squares method (PLS) in simultaneous spectrophotometric determination of zinc, copper and nickel in water samples has been studied. Compared with P matrix, K matrix and multiple linear regression, PLS has shorter operating time, more accurate and reliable results.
