中国科学技术大学金谷等研究了在KI及非离子表面活性剂存在下用罗丹明B(Rhm B)在水相测定微量铋的高灵敏度方法。配合物的最大吸收(λ_(max))在605nm处,表观摩尔吸光系数ε_(605)=2.88×10~5。在0～
University of Science and Technology of Japan Gukui studied KI and non-ionic surfactants in the presence of rhodamine B (Rhm B) in the aqueous phase determination of trace amounts of bismuth in high sensitivity method. The maximum absorption (λ max (max)) of the complex at 605 nm, the apparent molar absorptivity ε 605 (605) = 2.88 × 10 5. In 0 ~
