Abstract:V sklopu doktorske disertacije smo proučili, ali je mogoče iz rdeče sadre, ki trenutno predstavlja odpadek in obremenjuje okolje, pripraviti učinkovit adsorbent, ki bi bil uporaben za čiščenje odpadnih vod različnih pH vrednosti. Na učinkovitost posameznih adsorbentov ima velik vpliv način sintetiziranja kakor tudi raztopina, ki jo želimo čistiti. V sklopu priprave adsorbenta smo spreminjali koncentracijsko razmerje vhodnih surovin, temperaturo priprave adsorbenta, čas mešanja, intenziteto mešanja in preverjali učinek različne količine dodanega adsorbenta na potek adsorpcije. Analizirali smo lastnosti adsorbenta in preverili njegovo učinkovitost. Rezultate smo primerjali z rezultati, ki smo jih dobili z uporabo zeolita, bentonita in bele žlindre, kakor tudi z rezultati različnih avtorjev.

Title:Preparation and application of red gypsum adsorbent for waste water treatment
Abstract:As part of the doctoral dissertation, we examined whether it is possible to prepare an effective adsorbent from red gypsum, which is currently waste and burdens the environment, which would be useful for cleaning wastewater of different pH values. The efficiency of individual adsorbents is greatly influenced by the method of synthesis as well as the solution to be cleaned. As part of the preparation of the adsorbent, we changed the concentration ratio of the input raw materials, the temperature of the adsorbent preparation, the mixing time, the intensity of the mixing and checked the effect of different amounts of added adsorbent on the course of adsorption. We analyzed the properties of the adsorbent and checked its effectiveness. The results were compared with the results obtained using zeolite, bentonite and white slag, as well as with the results of various authors.
