Biochar is an eco-friendly amendment for the remediation of soils contaminated with cadmium (Cd). However, little attention has been paid to influence and underlying mechanisms co-pyrolyzed biochar on bioavailability uptake Cd in paddy soils. The current study explored effects from peanut shells (P) maize straw (M) at different mixing ratios (1:0, 1:1, 1:2, 1:3, 0:1, 2:1 3:1, w/w), bacterial community fractionation soil, its by rice plant. addition, particularly P1M3 (P/M 1:3), significantly elevated soil pH cation exchange capacity, transferred mobile residual fraction, reduced availability rhizosphere soil. application decreased concentration tissues (root, stem, leaf, grain) 30.0%- 49.4%, compared control. Also, enhanced microbial diversity indices relative abundance iron-oxidizing bacteria Moreover, was more effective promoting formation iron plaque, increasing sequestration plaque than other treatments. Consequently, highest yield lowest accumulation were observed following application. This revealed feasibility applying facilitating Cd.

Review of modified biochar for removing humic acid from water: analysis of structure-activity relationship

Biochar, Год журнала: 2025, Номер 7(1)

Опубликована: Янв. 2, 2025

Abstract Humic acid (HA), as an important part of natural organic matter (NOM), is a precursor disinfection byproducts. HA affects the migration and transformation inorganic substances such metal ions, causing direct harm to ecological environment human health. Therefore, removal aspect geochemical research. In this review, research on application biochar modified biochar, which exhibit excellent capability, in treatment HA-like NOM water summarized. The different mechanisms via are discussed by analyzing structure-activity relationship under various influencing conditions. performance mechanism adsorption, Fenton, photocatalysis, electrochemical oxidation methods analyzed, their advantages disadvantages compared. Finally, potential development direction multifunctional materials for NOM, including HA, from reviewed. This review provides theoretical technical support using novel its actual bodies. Graphical

Industrial effluents contaminated with different types of organic dyes have become a major concern to environmentalists due the carcinogenic nature dyes, which are harmful human and aquatic life. In recent years, treatment by natural resources has been proposed as most sustainable solution for this problem. work, Moringa oleifera (M. oleifera) seed-derived biochar composites, e.g., Biochar-Chitosan (BC), Biochar-ZnO (BZ), Chitosan-ZnO (CZ) were produced characterized. The synthesized materials then utilized adsorb cationic dye, methylene blue. Spectroscopic analysis biochar-based composites revealed that modification chitosan ZnO introduced functional active groups in surface. Pore development structure nanocomposites was visible surface morphological images. derived fully amorphous increased crystallinity modification. obtained area varied from 0.90 ± 0.00 14.48 1.13 m2 g−1 prepared sorbents, where BZ corresponds highest BC lowest area, respectively. basic pH (9) favorable condition sorption. sorption reached equilibrium at 90 min. Isotherm favorability Langmuir model over Freundlich Temkin models. capacity (~170 mg/g) found BC. showed 75% increase 16% decrease removal modification, Response methodology (RSM) optimization similar results analytical experiments. characterization experimental prefigure chemical functionalities critical parameter adsorption process.
