摘要
采用原子吸收分光光度仪测定水松纸消解液中的重金属含量,通过对水松纸消解液进行直接过滤检测和分时静置检测,找出水松纸消解液最短静置时间或最佳过滤状态,以达到缩短水松纸重金属含量的检测时间。实验表明:水松纸消解液直接过滤或静置2h就可上机测定其重金属含量;消解液中重金属的损失比较小,相对标准偏差≤5%。
the content of heavy metals in the solution was determined by atomic absorption spectrophotometer.Through direct filtration detection and time-sharing static detection of the solution,the shortest static time or the best filtration state of the solution was found,so as to shorten the detection time of heavy metals in the solution.The results show that the content of heavy metals can be determined by direct filtration or by sitting for 2 hours.The loss of heavy metals in the solution is relatively small,and the relative standard deviation is less than 5%.
