用硝酸消解胶乳样品 ,以氨水溶解消解产物 ,加入磺基水杨酸与铁形成三磺基水杨酸铁配合物 ,以工作曲线法测定。建立了在氨性溶液中快速测定胶乳中铁的FAAS法。对样品处理方法、消解产物的溶解性质、磺基水杨酸铁配合物的稳定性、试液和空白溶液粘度一致性、线性范围及检出限进行了考察。测定结果的相对标准偏差为 5 6%,加标回收率 95 0 %～ 99 5 %。 With nitric acid digestion latex samples, dissolved in ammonia to dissolve the product, adding sulfosalicylic acid and iron to form a tri-sulfosalicylic acid iron complex, measured by the working curve. A rapid FAAS method was developed for the determination of iron in latex in ammoniacal solution. The sample processing methods, the dissolution properties of digestion products, the stability of iron sulfosalicylate complexes, the viscosity consistency of the test solution and blank solution, the linear range and the detection limit were investigated. The relative standard deviation (RSD) was 56% and the recoveries were between 95 0% and 99 5%.
