The Action of Organic Reagent Containing Sulfonic Acid Group in Flame Atomic Absorption Spectrometry 含磺酸基的有机试剂在火焰原子吸收光谱法中的作用
The pH value had the great influenced the Pb~ ( 2+) adsorption properties of ACF, whereas oxidized ACF, ACF with pendant sulfonic acid group and Na-type ACF had good adsorption properties in a quite wide range of pH values. pH值对ACF吸附铅离子有较大影响,氧化改性ACF、含磺酸基ACF和Na型ACF在较宽的pH值范围内保持着对铅离子较高的吸附性能。
The adsorption isotherms of ACF, oxidized ACF and ACF with pendant sulfonic acid group had good agreements with Langmuir isotherm and Freundlich isotherm model, and Na-type ACF had a good agreement with Langmuir isotherm model. ACF、氧化改性ACF、含磺酸基ACF的吸附等温线较好的符合Langmuir,和Freundlich吸附等温线模型,Na型ACF的吸附等温线较好的符合Langmuir吸附等温线模型;
