| 摘 要： | 用浓硝酸和高氯酸混酸体系在超声波作用下消解滤膜,加入稳定剂琼脂,用超声波震荡15min制成悬浮液,用火焰原子吸收光谱法测定TSP中的锌、铅和铁的含量,并以传统浓HNO3-H2O2湿法消解-原子吸收光谱法的测定结果为参考对测定值进行t检验,结果表明:RSD≤3.27%(n=6),两种方法的相对误差<±0.85%,且两种方法无显著性差异,说明悬浮液进样法的测定结果准确、可靠。

| Abstract: | Under the influence of ultrasonic wave,the filtering membrane was degraded in concentrated nitric acid and perchloric acid,followed by addition of agar as a stabilizing agent and ultrasonic oscillation for 15min to prepare suspended liquid.The content of zinc,lead as well as iron species in TSP was determined by flame atomic absorption spectrum(AAS).In reference to the result of traditional wet degradation by concentrated nitric acid-hydrogen peroxide,there was no distinct difference in t-validation,with RS... |
