The method of separation of sulfamat-ions

Анотація

        The method of separation of sulfamat-ions from aqueous solutions. The methodology is highly selective reaction of the sulfamat ions with mercury (II) ions, which leads to the formation of insoluble white sediment. This allows quantitatively separated sulfamat-ions, and ions of mercury from solution. At the same time increases the sensitivity (0.05 mg/cm3 method) and selectivity of the branch, with an accuracy within 1÷3% in heavily stained and concentrated solutions of back.

Using the proposed technique department sulfamat ions provides the following benefits:
- increased sensitivity to 0.05 mg / cm 3 with an error-ion separation sulfamat under optimal conditions within 1 ÷ 3%;
- significantly increases the selectivity of separation masking the presence of anions and cations;
- eliminated many inconvenient forum factors that prevented separation methods are known, in particular, provides the possibility of separation in highly colored and concentrated solutions of electrolytes background;
- provides replacement cost and not at all safe for the environment environmental indicator nitroprusside sodium and other accessible and cheaper to sulfamic acid salt.
