摘要
紫外光度法分析了萘、联苯和氧化联苯,采用偏最小二乘法(PLS),用计算机对测定信息进行处理,不经掩蔽和分离同时测定了混合体系中的萘、联苯和氧化联苯.试验结果表明,萘、联苯和氧化联苯的浓度分别在0～30mg·L^(-11),0～50mg·L^(-1)和0～50mg·L^(-1)范围内呈线性关系,对合成样品中这三种组分进行分析,结果满意.
It is reported in this paper that naphthalene, biphenyl and biphenylene oxide can be determined by UV-spectrophotometry in the presence of each other without separation using the PLS regression method. Linear relationships between the absorbance and concentration of the aboved mentioned compounds hold in the following range: for naphthalene 0-30mg ·L-1, for biphenyl 0-50mg·L-1and for biphenylene oxide 0-50mg· L-1.
