Pd/In-based catalysts for nitrate catalytic removal from water: synthesis designs aiming for better N2 selectivity

Green synthesis of polypyrrole-supported metal catalysts: Application to nitrate removal in water

Synthesis ratios of Mg-Al and Zn-Al layered double hydroxides efficiency and selectivity in nitrate removal from solution

Four diverse chlorides layered double hydroxides with diverse ratios, i.e. Mg-Al (3:1), Mg-Al (4:1), Zn-Al (4:1), and Zn-Al (3:1) LDHs, were prepared to evaluate their efficiency and selectivity towards nitrate removal from aquatic solutions. A batch experiment was done at the initial nitrate concentration of 5-1000 mg/L, pH 5 to 12, and contact time of 5-180 min. Isotherms of nitrate adsorptio...

Study of HMS Modified ZrO2 Supported Platinum Catalysts for Toluene Removal: Catalytic Combustion and Kinetics Study

Reaction behaviors and kinetics of catalytic oxidation of toluene with different feed flows over Pt/Zr(x)-HMS catalysts with Si/Zr ratio equal to 5, 10, 20 and 35 were investigated over a wide temperature range (200 – 500 oC). Results show that Pt/Zr(x)-HMS performs more easily toluene oxidation. The kinetic data were fitted by the Power-law and Mars–van Krevelen kinetic models. The fitting res...

Synthesis of Novel Magnetic Biochar Using Microwave Heating for Removal of Arsenic from Waste Water

Novel magnetic biochar has been successfully synthesized by using microwave technique, using discarded materials such as Empty Fruit Bunch (EFB). The optimized conditions for the best novel magnetic biochar synthesis are at 900 w reaction power, 20 min reaction time, and impregnation ratio 0.5 (biomas:FeCl3) The details physical and chemical analyses of novel magnetic biochar wer...

Investigating the efficiency of surface flow constructed wetlands by using Cyperus alternifolius plants for nitrate removal from water

Background and Objective: Synthetic wetlands are engineering systems that use natural plants, soils and organisms to purify municipal polluted water and remove nitrate. Materials and Methods: In this study, three systems were considerd as soil culture, three systems as plant cultivation on floating plates and three other systems without plant and porous bed as. The experiments were done three ...
