【摘要】 提出了用乳浊液作增敏剂的FAAS增敏方法。研究了由 3种有机溶剂 (苯、二甲苯、苯 丙酮 )、1种有机试剂 (邻苯二甲酸二丁酯 )、3种乳化剂 (Tween 80 ,TritionX 10 0 ,OP)组成的乳浊液对铁、镍、锌、锰、铅的增敏效应。结果表明 ,增敏效应显著 ,对以上 5种元素最大增敏百分数分别为 89% ,34 % ,12 1% ,38% ,6 9%。更多还原

【Abstract】 A enhancement method of FAAS with emulsion as enhancement agent has been developed.The enhancement effect of emulsion made of three organic solvents (benzene,benzene propanone,xylene),one organic reagent (dibutyl phthalate) and three emulsifiers (Tween 80,Triton X 100,OP) for iron,nickel,zinc,manganese and lead was studied.The results indicated that the enhancement is satisfactory.The emulsion with maximum enhancement percentage are respectively emulsion of benzene OP dibutyl phthalate with 89%,emulsion of xylene Trition 100 dibutyl phthal with 34%,emulsion of benzene Trition 100 with 121%,emulsion of benzene Trition 100 dibutyl phthalate with 38% and 69% in sequence of the above elements.更多还原
