One and the same amount of Hg_, R e does not interfere with the relative error is less than 5). Shows good selectivity of this Law, in particular Fe, 10000 times that do not interfere with, which is the normal dynamic method for determination of vanadium do not have the. Only e a serious interference, allowing only 0.2 times the amount of co-existence. , 3.8 3.8.1 Water samples taken directly 10mL machine well water analysis, and recovery test, results are presented in Table l3.8.2 sets James Bond kind of accurately weighed 0.05 ~ O. 10g samples, before adding hydrochloric acid 3mL,[link widoczny dla zalogowanych], together with nitric acid 2mL. Electric panel heating solution, evaporated, Add a few drops of sulfuric acid heated to smoke a lot of white smoke, Ling was, dissolved in water and transferred into the volumetric flask 100raL given volume of Analytical Chemistry Volume 24, according to sample weight and content of the sample after appropriate dilution certain amount of analysis, the results are listed in Table 1.
