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,abercrombie fitch outlet, together with nitric acid 2mL.
