- W3149446121 abstract "用 1-(2-thiazolylazo ) 的钴,铜和镍的同时的决心由 spectrophotometric 方法的 -2-naphthol (这篇文章的第一个数字) 是在分析化学的一个困难的问题,由于光谱干扰。由 multivariate 刻度方法,例如部分最少的广场(请) 回归,获得适应的一个模型是可能的在刻度使用的混合物的集中价值变化。直角的信号修正(振荡) 是使用基于抑制主要部件分析移开对目标变量无关的信息的一种预处理技术。振荡是一个合适的预处理方法为请没有用 spectrophotometric 的预言能力的损失的混合物的刻度方法。在这研究,刻度模型为钴,铜和镍的 21 不同混合物在 550 鈥 ? 50-nm 范围基于吸收系列。刻度矩阵从包含 0.05 鈥 ?.05, 0.05 鈥 ?.30 和 0.05 鈥 ?.80 渭 g mL 的样品被形成 ? 1 为钴,铜和镍分别地。为有振荡并且没有振荡的钴,铜和镍的预言(RMSEP ) 的根均方差是 0.007, 0.008, 0.011 和 0.031, 0.037, 0.032 渭 g mL ? 1 分别地。这个过程在合成、真实的样品和决心的好可靠性允许钴,铜和镍的同时的决心被证明。" @default.
