摘要
乙醇-明胶可以提高氯化银沉淀的稳定性,AEO-7表面活性剂对银原子化效率也有明显提高,本文在一定的介质条件及仪器分析条件下,通过加入乙醇-明胶和AEO-7,应用石墨炉原子吸收法测定银离子含量,从而间接测定高价稀土氧化物矿物中氯离子含量,其测定值为76.07μg/g ,相关系数r=0.9997, RSD=0.27%,加标回收率为92.5%～102.0%.
A rapid and simple method for the indirect determination of trace chlorine in high-valence rare earth oxide by GFAAS is reported. We apply Gelatin-Alcohol to extending stability of AgCl and AEO-7 to extending atomization efficiency. The relative standard deviation is found to be smaller than 0. 27%, and the recoveries are in the range 92.5%-102.0%, the relevant coefficient is 0. 9997.
