【摘要】 本文利用微色谱柱研究了甲基膦酸二甲庚酯（Ｐ３５０）对Ｇａ的吸附性能，在４ｍｏｌ／ｌＨＣｌ介质中镓的上柱率为１００％，吸附在柱上的镓可用１ｍｌＨ２Ｏ．１ｍｏｌ／ＬＨＣｌ或１．５ｍｏｌ／ＬＨＢｒ洗脱，在３ｍｍ色谱柱上的吸附容量为１８．２ｍｇ／ｇ干树脂。同时采用静态法研究了酸度，时间、温度、浓度等因素对吸附的影响更多还原

【Abstract】 The separation and determination of trace Gallium with P 350 extraction-eluation resin is studied .The Gallium is quantitatively adsorbed on chromatographic micro column with 3 mm form 4 mol/L HCl or 6 mol/L HBr solution and eluted with 1 ml H 2O 1 mol/L HCl or 1.5 mol/L HBr The dynamic and static adsorption capacity of resin to Gallium is 18.2 mg/g and 12.4 mg/g dry resin respectively .It is studied that acidity time rate and constant make effect absorption reaction by using static state method .更多还原
