摘要
测定了α-萘酚、α-萘胺和2,7-二羟基萘混合体系的紫外光谱,用目标因子分析成功地确定了混合体系的物种数、物种种类以及各物种的含量。讨论了波长范围、波长间隔选择对分析结果的影响。平均回收率α-萘酚为94.84％,α-萘胺为108.29％,2,7-二羟基萘为101.66％。并将结果同偏最小二乘法做了比较。
The UV-spectra data of mixture solutions, which consist of α-Naphthol, α-Naphthylamine and 2,7-Dihydroxy-naphthalene, were measured. Number, identities and concentrations of every compound involved are determind successfully by directly using Target Factor Analysis technique. The effects of wavelength range and samplin8 interval selected on the results have been discussed. The averase recoveries are 94.84％ for NAP, 108.29％ for NAA, 101. 66％ for DHN respectively. The results obtained are compared to those by Partial Least Square method.
