Developing of high-performance carbonaceous materials from biomass is a significant contemporary research subject to meet the increasing demand for functional adsorbents with low price, high available and sustainability for adsorptive removal processes of industrial pollutants. The present work investigates formation of nanostructured surface modified P-doped activated carbon (ACP) materials via thermochemical activation of orange peel (OP) biomass residual materials, by ... إقراء المزيد

A SERIES OF LAFEO3 PEROVSKITE NANOPARTICLES (NPS) WERE SUCCESSFULLY FORMED BY A DIRECT SOL-GEL METHOD INVOLVING DIFFERENT CITRIC ACID TO METAL RATIOS OF X (WHERE X = 2–16). THE RESULTED PRECURSORS WERE TREATED VIA AUTO-COMBUSTION, FOLLOWED BY CALCINATION AT DIFFERENT TEMPERATURES (300–700 C). SIZE-CONTROLLED LAFEO3 NPS WERE GETTING SMALLER DOWN TO 18.8 NM AT HIGH CITRIC ACID RATIO, SHOWING RELATIVELY ... إقراء المزيد

The removal of heavy metals pollutants from contaminated water by adsorption is one of the most effective physicochemical techniques. The recycling approach of residual biomass into adsorbent materials, has received increasing attention for biomass valorization. In effort for Orange peel (OP) biomass valorization, the conversion of OP into phosphorous (P)− doped activated carbons (ACP) materials was investigated via phosphoric acid ... إقراء المزيد

PHENOLIC POLLUTANTS ARE VERY TOXIC AND THEIR REMOVAL FROM AQUATIC RESOURCES IS VERY IMPORTANT. ADSORPTION BY ACTIVATED CARBON, AC, IS THE BEST METHOD FOR REMOVAL OF PHENOLS FROM SOLUTIONS. HOWEVER, THE HIGH COST OF AC AND DIFCULTY OF ITS REGENERATION AFTER PHENOL ADSORPTION PUTS HIGH DEMAND ON LOW PRICE AC MATERIALS. THEREFORE, SUGARCANE BAGASSE AS A SUSTAINABLE, BULKY AND FBROUS ... إقراء المزيد

MAXSORB III IS THE BEST AVAILABLE MICROPOROUS ACTIVATED CARBON. THE PARENT MAXSORB III HAS BEEN MODIFIED BY PYROLYSIS IN THE PRESENCE OF AMMONIA CARBONATE. THE ADSORPTION ISOTHERMS AND KINETICS OF HFC404A ONTO THE MODIFIED MAXSORB III ARE EXPERIMENTALLY MEASURED OVER 25 °C TO 75 °C. TÓTH AND DUBININASTAKHOV MODELS ARE UTILIZED TO FIT THE EXPERIMENTALLY MEASURED DATA. THE ISOSTERIC HEAT ... إقراء المزيد
