- The results indicate that the recoveries of iodine are different in different acid digestion conditions.
- The results of determination were compared with those of acid digestion at atmosphere and both of them are same.
该法准确、快速、简便 ,与常压酸消解法比较 ,结果基本一致 ,已用于蘑菇中痕量铅的测定
- Nitric-perchloric acid digestion and antimony salt-phosphomolybdate blue spectrophotometry were used to determine the trace phosphorus in the residual detergents, and an analytic method was thereby established.
- The paper uses typical sample plot method of forest ecology to obtain field data,and the Walkley-Black acid digestion method for measuring the carbon in the forest and soil is used in this paper.
- Microwave-assisted acid digestion was best among the three methods and was characterized with convenient,rapid,effective,unnecessary close attention,less pollution and high recoveries for sample preparationof all solid wastes.
- The monitoring methods to detect phosphoric acid fume in phosphorylation workshop was made up with perchloroethylene filter membrane sampling acid digestion molybdenumblue spectrophotometry.
