Highly Sensitive Spectrophotometric Determination of Trace Amounts of Uranium ( Ⅵ ) with Thiocyanate-Basic Xanthene Dye-Gum Arabic Systems

Spectrophotometric determination of molybdenum, zinc, cobalt(Ⅱ), indium, selenium (Ⅳ), iron (Ⅲ), vanadium (Ⅴ), which is based on the ion-associate complexes formed by the reaction of metal ion-thiocyanate anionic complexes with some basic dyes in aqueous solution in the presence of a surfactant has been reported.

共振瑞利散射法测定硫氰酸盐-碱性三苯甲烷染料体系中的痕量钼

研究了钼（Ⅴ）与硫氰酸盐和结晶紫、乙基紫、孔雀石绿、亮绿及碘绿等５种碱性三苯甲烷染料形成离子缔合配合物的共振瑞利散射光谱．考察了它们的光谱特征、影响因素和适宜的反应条件，确定了共振瑞利散射强度与钼（Ⅴ）浓度之间的关系．方法灵敏度高，不同体系对钼的检出限在２．１～１２．０μｇ／Ｌ之间，提出了用共振瑞利散射测定钼的新分析方法。

钼(Ⅴ)-硫氰酸盐-碱性三苯甲烷染料体系的二级散射光谱及其分析应用

研究了钼（Ⅴ）硫氰酸盐配阴离子与结晶紫、乙基紫、孔雀石绿、亮绿及碘绿等碱性三苯甲烷染料的离子缔合配合物的二级散射和反二级散射光谱．考察了影响因素、适宜条件和分析化学特征．提出了用二级散射光谱法测定钼的新的高灵敏分析方法，可用于钢铁中痕量钼的测定．
