摘要
针对标准法测定总铬存在的诸多不足,提出了烘箱法测定总铬的新方法。改进法制作的校准曲线相关系数γ】0.999,相对标准偏差RSD【0.88%,加标回收率为98.3%~101.7%,均优于标准法。
There are quite a lot flaws by using standard methods to monitor total chromium.One new method called oven drying method was pointed out.The results illustrated that the relative coefficient was more than 0.999,with more than 0.88% of relative standard deviation.At the same time,the recovery rate was from 98.3% to 101.7%,all of which was prior to the standard method.
