Spent caustics contain compounds such as mercaptans, sulfides, and phenols. In addition,
spent caustic solutions are highly alkaline and have high chemical oxygen demand. There …

The feasibility of using biochar as a sorbent to remove nine halogenated phenols (2, 4-
dichlorophenol, 2, 4-dibromophenol, 2, 4-difluorophenol, 2-chlorophenol, 4-chlorophenol, 2 …

To evaluate the adsorption mechanism and performance of phosphate onto the composite of
low-cost biochar and iron oxide, four biochar–iron oxides, namely biochar–magnetite (BC …

This work explored the efficiency and mechanisms of phosphate (P) removal by Ca-
impregnated biochar prepared from CaCl2-pretreated ramie stem (Ca-RSB) and ramie bark …

In the present study, dead biomass of marine macro algae, Kappaphycus alverezii (K.
alverezii) was used for the removal of phosphate from water. The effect of different …

The objective of this study was to assess the effect of biochar on growth and metabolism of
spinach (Spinacia oleracea L.) and mustard (Sinapis alba L.) planted in crop rotation …

In this study, a new low-cost magnetic composite comprising biochar-steel dust wastes was
fabricated by the facile co-pyrolysis method at different proportions of steel dust wastes. The …

Non-renewable phosphorus (P) resources are intensively declining and recyclable P is high
in demand for agricultural sector. Biochar as a renewable source of P and its …

Low cost biosorbents have gained considerable importance in the past decade for their
removal efficiency of contaminants from wastewaters. Both removal and recycle of the …

Dolochar, a solid waste generated from sponge iron industry during the process of direct
reduction of iron by rotary kiln, is explored as an adsorbent for phosphate removal in this …
