Head Belikov Kostyantyn Mykolajovich, Кандидат хімічних наук Registration Date 22-05-2018 Organization State Scientific Institution "Institute for Single Crystals" of National Academy of Sciences of Ukraine popup.description2 The following analytical methods have been developed: determination of the water content in the range 2 · 10-2-100% by weight; spectrophotometric procedure for the determination of hydroxide ions up to 5 ? 10-5%; voltammetric methods for determining the content of copper and lead with a determination limit of 2?10-6% by weight; flame-spectrometric methods for determining Na, K, Mg, Ca, Ba in the range of mass fractions 2·10-5 - 2·10-1%; electrothermal atomic absorption method of determination up to 5·10-6 wt.% of aluminum, chromium, manganese; a method for the determination of alkaline-earth and heavy metals up to 1·10-5 wt % by an atomic-emission method with inductively coupled plasma. The developed methods allowed systematic monitoring of the purity of samples of strontium iodides and europium. The level of impurity content in hydroxide and strontium carbonate which are used as starting compounds for the production of strontium iodide is established. Product Description popup.authors В.В.
