ANTIMICROBIAL PROPERTIES OF HYDROXYAPATITE MATERIAL OBTAINED BY GREEN TECHNOLOGY PATHWAY
Due to increasingly intense problems in terms of resistance to various types of infections, including bacterial resistance to antibiotics, new materials with effective contact antimicrobial action are intensely being researched. Hydroxyapatite (HAp) represents the leading material from the calcium-phosphate group, which can be used as a biocompatib...

PRELIMINARY ASSESMENT OF THE USE OF RED MUD SLAG FOR PHOSPHATE SORPTION FROM AQUEOUS SOLUTIONS
This paper shows the preliminary results of the investigation of the possibility of the use of red mud slag (RMS) for phosphate sorption from aqueous solution. The red mud slag was obtained from red mud treatment, specifically carbothermal reduction at high temperatures. This process resulted in forming a metallic phase (iron) and slag enriched wit...

PROCEDURES OF CHEMICAL WASTEWATER PURIFICATION OF GALVANIC CHEMICAL PROCESSES AND QUALITY OF PURIFIED WATER
The procedures of chemical purification of wastewater with chemical changes of polluting (harmful) water substances are: neutralization - adjusting the pH value by adding acids or bases; flocculation (flocculation) – joining of dissolved particles into larger flakes that settle; coagulation (coagulation) – addition of chemical substance...
