对于粮食中微量钴含量的测定,我们可选择采用石墨炉子吸收分光光度法则。根据实验条件的选择,该测定法灵敏度比较高,重现性较好,回收率为为96~102%,检出限可达0.2μg/ml,常见元素不干扰对粮食中钴的测定,可以得到满意结果。
對于糧食中微量鈷含量的測定,我們可選擇採用石墨爐子吸收分光光度法則。根據實驗條件的選擇,該測定法靈敏度比較高,重現性較好,迴收率為為96~102%,檢齣限可達0.2μg/ml,常見元素不榦擾對糧食中鈷的測定,可以得到滿意結果。
대우양식중미량고함량적측정,아문가선택채용석묵로자흡수분광광도법칙。근거실험조건적선택,해측정법령민도비교고,중현성교호,회수솔위위96~102%,검출한가체0.2μg/ml,상견원소불간우대양식중고적측정,가이득도만의결과。
For the determination of trace cobalt content in the food, we can choose to use graphite furnace absorption spectrophotometer.According to the choice of experimental conditions,the determination method of high sensitivity,good reproducibility,recovery is 96~102%, the detection limit of 0.2 mu g/ml,common elements do not interfere with the determination of cobalt in the food, you can get satisfactory results.
