摘要
Abstract
To compare the effects of the determination of phosphorus content by Phosphorus Vanadium Molyb-denum (P-V-Mo) yellow colorimetric method,total phosphorus contents were analyzied by this method in 10 different varieties of indica rice samples and 20 surface water samples from different sites. The results show that the total phosphorus content of rice samples ranges from 0.363 to 0.568 mg∕g and that of water samples ranges from 0.017 to 0.094 μg∕mL; there is little disturbance in the determination of rice samples by P-V-Mo yellow colorimetric method. In the determination of water samples,the suspended solid content and the turbidity of water samples have some effects on the accuracy of the determination. P-V-Mo yellow colorimet-ric method with easy and fast operation is suitable for the determination of indica samples and water samples with the total phosphorus content more than 0.017 mg∕L.关键词
