    ВОЗМОЖНОСТИ ПРИМЕНЕНИЯ МОЛДАВСКИХ ПРИРОДНЫХ СОРБЕНТОВ В НАРОДНОМ ХОЗЯЙСТВЕ РЕСПУБЛИКИ
    (2006) Пушняк, А.; Тутован, Елена; Зеленцов, Вячеслав; Стрелков, Е.; Покатилов, Виктор; Белевский, С.
    In present work the review and characteristics of the most important natural sorbents of Moldavian diatomites, bentonites and trepels are given. The experimental results of investigation of sorptional epuration of residual model solutions from heavy metals and colours by initial and modificated sorbents are discussed. The perspectives of use the natural sorbents of Moldavian in different fields of national economy of Republic are shown.

    СВОЙСТВА И ПОРИСТАЯ СТРУКТУРА МОДИФИЦИРОВАННЫХ ОТХОДОВ ВИНОДЕЛЬЧЕСКОЙ ПРОМЫШЛЕННОСТИ
    (2005) Зеленцов, Вячеслав; Дацко, Татьяна; Ковалёв, Виктор
    Two methods of modification of benthonite used in vine clarification have been applied: introduction of Na2S in report 1:10 into benthonite paste followed by pyrolysis at 450oC; electrotreatment of slime suspension in electrochemical cell (in anodic camera and in diaphragmless electrolizer). By means of thermogravimetric analysis some thermal effects attributed to different processes have been observed: removing of water (dehydratation), phase transformations, oxidation of organic compounds, crystallization and destruction of benthonite structure. Adsorption-structural characteristics of initial and modified samples of benthonite slimes have been examined and the mechanism of their change under thermo- and electrotreatment has been discussed.
