In the present work we have considered two alkali metals - sodium and potassium - at their molten stage near the melting point. For the purpose of this theoretical investigation we have used Harrison’s first principle (HFP) pseudopotential technique which... see more

A study of the products of ferritization processing of galvanic waste: sludge and spent process solutions is carried out. As a result of experiments on dynamic leaching of heavy metal ions, the immobilization properties of the sludge, obtained at differen... see more

Research analysis aimed at stabilizing processes in industrial waste and other, similar hazardous ion containing materials, shows that these materials can be successfully stabilized, if they are bound as a mineral component in cement. Considering that aur... see more

This study aims to know the effect of contextual teaching material towards undergraduate students’ learning outcomes in inogranic descriptive chemistry course. The research method used in this study is quasi experiments with posttest only control group de... see more

Terak timah yang merupakan limbah peleburan timah memiliki potensi untuk dapat dimanfaaatkan lebih lanjut dengan mengekstrak logam-logam berharga di dalamnya, seperti logam tanah jarang (LTJ). Tujuan penelitian ini adalah untuk menentukan kondisi optimal ... see more

Electric Arc Furnace (EAF) slag containing larnite, gehlenite, wuestite, montcellite and calcite as the main crystal phases was alkali activated using the alkali activator prepared by the mixing of two solutions, sodium silicate and NaOH. Alkali Activated... see more

Distribution of A and B isomers of crown-ether DC18C6 on their organic and water phases (chloride, nitrate and sulphocyanide salts) and extraction of alkali and earth alkali metals has been studied. In LiCl 0.1 M environment, lithium extraction could be i... see more

The object of the study is compositions of common alkali activated concretes using red mud as an active aggregate. The main problem when working with red mud is its chemical composition and high specific surface area, which quite negatively affect the pro... see more
