Influence of different pyrolysis temperature on the characteristics of forestry waste biochar for sodium adsorption
Journal of Material Cycles and Waste Management(2023)
Abstract
Soil salinization is a major problem affecting agriculture globally. One approach to restore saline soil is through the application of biochar which is great at adsorbing salt ions and thus amending salt-affected soils. Biochar produced using forestry wastes (Gigantochloa levis and Melaleuca cajuputi) were pyrolyzed at 300, 450 and 600 ℃ for 2 h. Proximate and ultimate analyses were done followed with physical and chemical analyses of the biochar and their raw materials before undergoing the sodium adsorption study. The fixed carbon was observed to increase from 9.636 to 72.919
