Determination of Trace Phosphorus by Laser Thermal Lens Spectrophotometry: Comparison between Molybdenum Blue and Malachite Green Methods 测定痕量磷的激光热透镜光谱法&钼蓝法与孔雀绿法的比较
A simple and effective method for the determination of trace phosphorus by laser thermal lens spectrophotometry with molybdenum blue or malachite green is presented in this paper. 采用激光热透镜光谱法(LTLS),分别以孔雀绿-磷钼杂多酸缔合物法和磷钼蓝法对痕量磷进行了测定;
Three kind of sludge adsorbents are long to the methylene blue adsorption time comparison, about 14h. The adsorption time of alkali sludge adsorbent to malachite green is shortest in the experiment and about 2h may achieve the adsorption equilibrium. 三种污泥吸附剂对亚甲基蓝的吸附时间比较长,都在14h左右。碱化污泥对孔雀石绿的吸附时间最短,2h左右就可达到吸附平衡。
Formation of a new ionic association species was observed between cation of the ionic liquids and anion of the cationic dyes ( methylene blue and malachite green). 在测定阳离子染料(亚甲基兰、孔雀石绿)在离子液体-水体系间分配系数的基础上,观察到一种新的离子缔合物。
The adsorption capacity for Methylene blue was higher than that of Malachite Green on the same initial concentration. 在相同的初始浓度下,硅藻土对亚甲基蓝的吸附容量高于孔雀石绿。
