WebNov 1, 2024 · The purpose of this study was to develop an efficient method of biochar modification for effective removal of Se(VI) ions from water. Commercially available biochar produced from wheat straw was impregnated by Fe(NO 3) 3 (0.8, 4 and 10% w/v) and pyrolyzed at 200 °C. Optimum pH, adsorption kinetics, and Se(VI) adsorption isotherms … WebIn this work, different biochar-based metal catalysts were tested for mid-temperature (400−600 °C) acetic acid steam reforming. K, Co, Ce, Fe and Ni were …

WebMar 5, 2024 · Compared with existing impregnation methods, bioleaching was facile, cheap and green, and deserved more concern. • High amount of Fe is loaded to biochar … WebMay 17, 2024 · 3.3 Effect of impregnation on biochar surface morphology. The morphology of the Fe-impregnated biochar samples prepared by pre- and post-pyrolysis was analyzed by SEM with magnification 250× (Fig. 4). The images mainly showed the difference in structural characteristics at each ultrasonic pre-treatment level. WebCorn stover biochar (CSB) and maple biochar (MB) were added into anaerobic digesters and evaluated for hydrogen sulfide (H 2 S) reductions. This was the first study to show Fe-impregnated biochar can eliminate H 2 S production. The novel study evaluated biochar addition on H 2 S reduction and nutrient concentrations using three experiments to test … diagnosis sound problems
