Article Abstract
Wastewater containing phosphorus is often added by industrial activities, which is bad for the environment. In this study, composite biochar (PG-RS700) was prepared from phosphogypsum (PG) and rape straw (RS) for the treatment of phosphate in wastewater. SEM, FTIR, XRD and XPS characterization results showed that PG and RS were successfully combined. When PG-RS700 was dosed at 1.5 g/L and the phosphate solution concentration was 50 mg/L and pH = 8, the phosphate removal rate was 100% and the adsorption capacity was three times higher than the corresponding pure PG and RS. The quasi-secondary kinetic model indicated that the adsorption mechanism was chemisorption, and the maximum adsorption capacity for phosphate in the Langmuir isotherm model was 102.25 mg/g. Through pot experiment, the phosphorus adsorbed material obviously promoted the growth of plants. PG-RS700 can be used as a powerful adsorbent to treat phosphate in water and return it to soil as phosphate fertilizer.

This study investigated the pyrolysis of mixed medical waste (MMW) in an indirectly heated rotary kiln, focusing on the effects of operating parameters (filling ratio, heat source temperature, and rotation speed) on the heat transfer performance and product distribution. The pyrolysis behaviors of individual components (cotton swabs, paper, bandages, and plastics) and their composite mixtures were characterized using thermogravimetric-differential thermal analysis (TG-DTA). The heat transfer characteristics, chemical reaction properties, kiln operating parameters, and interactions between the processes were also investigated.

A free radical polymerization approach was applied to synthesize different carboxymethyl cellulose-grafted poly(acrylamide) hydrogels (Hyd) composited with biochar, magnetic biochar, and magnetic biochar decorated with ZIF-67 to decontaminate methylene blue (MB) from water media. Biochar was obtained from walnut shells (WS) by a pyrolysis method, and magnetic biochar (WS/CoFeO) and biochar-decorated ZIF-67 (WS/CoFeO/ZIF-67) were prepared by chemical co-precipitation and hydrothermal methods, respectively. An increase in the amount of these particles by up to 10 wt% enhanced the removal performance.

Water eutrophication has emerged as a pervasive ecological challenge worldwide. To realize the resource utilization of waste and nutrients, a novel rape straw-derived biochar-calcium alginate composite (M-CA-RBC) immobilized Pseudomonas sp. H6 was synthesized to simultaneously remove phosphate (PO) and ammonium (NH) from distillery wastewater.

Black morel (Morchella sextelata) is widely regarded as a post-fire mushroom because of its prolific fruiting in post-fire forest soils enriched with charcoal. Intriguingly, artificial cultivation of M. sextelata often incorporates biochar as a soil amendment to enhance yield, although the underlying physicochemical and ecological mechanisms remain unclear.

Herein, ball-milled magnetic biochar-vermiculite composite (MBC@VT) and ball-milled magnetic biochar-zeolite composite (MBC@ZT) were synthesized via one-step ball-milling, and their adsorption capacities for Pb(II)/P-nitrophenol (PNP) in water were compared. The results demonstrated that the removal of Pb(II) and PNP through both materials was a complex, endothermic reaction mainly driven by chemisorption, with strong tolerance to pH changes and co-existing ions. MBC@VT showed superior adsorption for Pb(II) (reaching 367.
