银-铜-铁-镍体系测定条件的旋转设计优化和目标转换因子分析法的同时测定

Optimization of Experimental Parameters of Copper, Silver,Iron and Nickel by the General Revolving Combination Design and Simultaneous Spectrophotometric Determination with Target Factor Analysis

利用二次通用旋转组合设计的方法 ,建立了吸光度与显色剂、增敏剂用量以及p H值之间的数学模型 ,进而得到使吸光度最大的显色剂用量、增敏剂用量及 p H值。在此优化的基础上 ,用目标转换因子分析分光光度法对银、铜、铁、镍的合成样品的合谱进行了解析处理 ,得到较为满意的结果。

The general revolving combination design is used to establish a mathematical model describing the relationship between the absorption and the quantity of SDS, 5 Br PADAP and pH. The optimum experimental conditions are obtained with this mathematical model. Under the optimum conditions, the TFA spectrophotometry is used to determine Cu, Ag, Fe, Ni in synthetic samples with satisfactory results.
