查询词典 dye

Resonance light scattering spectrum of cadmium- phenanthorline- bromophenol blue system has been studied. The effects of interference substances and optimization of procedure have been investigated. In the presence of Tris-HCl(pH=9.60),Cd2+ reacts with Phen to form the chelate cation, which further reacts with acid dye of BPB to form an ion-associated complex. Then, the complex molecules are accumulated to particles by virtue of hydrophobic forces and other molecular forces. This results in significant enhancement of RLS intensity, and the enhanced intensity of RLS at 638nm is proportional to the concentration of Cd~(2+).

研究了镉-邻菲罗啉-溴酚蓝体系在碱性条件下的共振光散射光谱特征，考察了体系的影响因素和最佳反应条件，研究表明，在pH=9.60的Tris-HCl介质中，镉与邻菲罗啉形成络阳离子，再与酸性染料溴酚蓝形成离子缔合配合物，在疏水力等分子间作用力下，缔合物分子聚集形成缔合微粒，溶液的共振散射光显著增强；在638nm处RLS增强程度与镉浓度成线性关系，线性范围为0-3.20mg/L，检出限为4.50ug/L。
