WebDec 3, 2014 · It has a high specific surface area, a high density of negative surface charges, and characteristic pores and surface functional groups . Biochar has been reported to be able to improve soil fertility by sequestrating C and enhancing retention of nutrients – and to suppress greenhouse gas emissions to the air . WebBiochar (BC) is one of the many soil amendments. Because of its special structure and property, such as huge specific surface area, its richness in oxygen-containing functional groups, and a large number of surface charges, BC could be an alternative absorbent.

WebApr 15, 2014 · Biochar is a promising alternative to remedy the soils contaminated with heavy metals and organic compounds through adsorption and immobilization due to its large surface area, charged surface, and functional groups. Overall, the bioavailability of heavy metals and organic compounds decreases when biochar is amended into soils. WebAbstract. A multi-technique analysis was performed on a range of biochar materials derived from secondary organic resources and aimed at sustainable recovery and re-use of wastewater phosphorus (P). Our purpose was to identify mechanisms of P capture in biochar and thereby inform its future optimisation as a sustainable P fertiliser.
