| 摘 要： | 本文研究了在三酸即盐酸、硝酸、高氯酸存在的条件下,地质样品于中温电热板上进行热分解,至样品冒高氯酸白烟,其目的赶尽硝酸,趁热加入盐酸将锡还原成低价,再用硫脲-抗坏血酸为掩蔽剂,消除铁、镍等过渡金属元素的干扰,用氢化物原子荧光光度法测定化探样品中锡的量。此方法在酸度、灯电流、硼氢化钾浓度、还原剂等众多因素进行了改进,经国...

| Abstract: | Under the conditions of hydrochloric acid,nitric acid,and perchloric acid,decompose geological samples in the intermediate temperate hot plate to take samples of white smoke,which aims to rush to make nitric acid,adding hot hydrochloric acid reduced low tin,and then thiourea-ascorbic acid as a masking agent to eliminate iron,nickel and other transition metal elements of interference with hydride generation atomic fluorescence spectrometry to determine the amount of tin in geochemical samples.This method acidity,lamp current,the concentration of potassium borohydride,reducing agents and many other factors were improved by the national standards for the validation sample,this method is simple,reliable,high sensitivity and low detection limit,the determination results in the allowable range. |
