Influence of shungite treatment methods on its absorption properties and on water treatment quality for beverages production
(2019) Oliynyk, Svitlana; Melnyk, Lyudmila; Samchenko, Iryna; Melnyk (Tkachuk), Nataliia; Loginova, Olga; Kisterska, Ludmyla
The use of shungite activated steam treated and modified by nanosilver provides increased efficiency of cleaning of harmful impurities and stabilization of the redox potential of the prepared water. Використання шунгітової активованої пари та модифікованого срібла забезпечує підвищену ефективність очищення шкідливих домішок та стабілізація окислювально-відновного потенціалу підготовленої води.
He use of sulphophtalein dyes immobilized on anionite AB-17x8 to determine the contents of Pb(II), Cu(II), Hg(II) and Zn(II) in liquid medium
(2017) Kostenko, Elizaveta; Melnyk, Lyudmila; Matko, Svetlana; Malovanyy, Miroslav
The conditions of the immobilization of xylenol orange, methylthymol blue, pyrocatechol violet, and chromazurol S at the surface of AB-17×8 anionite were studied. The interaction of Cu(II), Pb(II), Zn(II), Hg(II) ions with obtained solid-phase reagents was investigated. The efficiency of the purification of apple juice with such natural adsorbent of Cherkasy deposits (Ukraine) as palygorskite was studied. The optimum conditions of the reactions, quantitative characteristics of the composition and the surface compound stability, the efficiency of the anion exchanger with the immobilized sulphophthalein dyes were determined.
Adsorption of heavy metals ions from liquid media by palygorscite
(2015) Melnyk, Lyudmila; Bessarab, Alexander; Matko, Svetlana; Malovanyy, Miroslav
Досліджено процес адсорбції природним мінералом палигорскітом важких металів із стічних вод і харчових продуктів (яблучний сік). Вивчено процеси вилучення міді, кадмію, свинцю, ртуті та цинку. Визначено раціональні технологічні параметри цих процесів. Встановлено механізм адсорбції важких металів з яблучного соку палигорскітом.
Water-alcohol adsorbing cleaning out of higher alcohols by shungite
(2014) Melnyk, Lyudmila; Turchun, Oleg; Melnyk (Tkachuk), Nataliia; Kuts, Anatoly; Melnyk, Zinoviy
The aim of the research work is to increase the quality and safety of high spirits solutions at the expense of using natural adsorbent shungite.
Methods of recovering schungite’s adsorptive properties after processing red beet juice
(2013) Melnyk, Lyudmila; Melnyk, Zinoviy; Krivorotko, Volodimir
Shungita investigated regeneration techniques for reuse in the production technology of red beet juice. The expediency of using the method of regeneration shungita superheated steam certain parameters.
Microbiological, Physico-Chemical and Organoleptic Parameters of Apple Juice, Processed by Shungite
(2013) Melnyk, Lyudmila; Bessarab, Alexander; Matko, Svetlana
This paper is dedicated to results of studying microbiological, physico-chemical and organoleptical parameters of apple juice processed by shungite. Shungite is a natural mineral which has special structural composition, characterized by the existence of fullerenes and nanotubes. This paper explains the methods applied by the authors to prepare shungite for experimental research, to process apple juice by adsorbent, to determine the quantity of microorganisms in juice after it interacted with shungite, weight percentage of dissolvable dry solids, active acidity and quality parameters. In juice, processed by shungite, bacteria, fungi and yeast were detected. The authors made a comparison between microbial population in juice before and after its interaction with shungite. The paper refers to method under which shungite adsorbs bacteria, fungi and yeasts. The authors presented the results of studying dry solids content, active acidity of apple juice, processed by shungite at various temperatures and conducted assessment of apple juice quality after its interaction with sorbent. Through their research, the authors established rational parameters of apple juice processed by shungite under which the maximum reduction of microbial insemination is reached. The research proved that after apple juice interacts with shungite, its dry solids content and active acidity level remain unchanged. This paper confirmed high quality parameters of apple juice processed by shungite. Taking into account the obtained results, the authors concluded that use of shungite to process apple juice does not require expensive equipment, complex maintenance of the processing procedure, which reduce the cost value of a manufactured product.
