FeLaO fabricated biochar for removal of phosphorus in water and exploration of its adsorption mechanism.

Phosphorus (P) runoff from untreated wastewater and agricultural runoff has become an issue of concern because excessive P is detrimental to the health of water bodies and aquatic organisms such as fishes. Hence, different methods are being developed to salvage this challenge. However, most of the methods are expensive, while some are unsustainable.

Hydrothermal carbonization of alfalfa: role of processing variables on hydrochar properties.

Hydrothermal carbonization of alfalfa is a potential way to reuse agricultural waste. However, the effects of hydrothermal conditions on the properties of alfalfa-derived hydrochar are not clear. Herein, this study investigated the impact of different synthesis conditions (e.

Enhanced phosphate scavenging with effective recovery by magnetic porous biochar supported La(OH): Kinetics, isotherms, mechanisms and applications for water and real wastewater.

Herein, La(OH) decorated magnetic porous biochar (MPBC) was synthesized via KHCO activation and hydrothermal processes. The La-to-MPBC mass ratio of 3:1 described as La-MPBC possessed a monolayer phosphate adsorption capacity of 116.08 mg/g across a pH range of 3.

Monobutyl phthalate (MBP) induces energy metabolism disturbances in the gills of adult zebrafish (Danio rerio).

Monobutyl phthalate (MBP) is a primary metabolite of an environmental endocrine disruptor dibutyl phthalate (DBP), which poses a potential threat to living organisms. In this research, the acute toxicity of MBP on energy metabolism in zebrafish gills was studied. Transmission electron microscopy (TEM) results show that 10 mg L MBP can induce mitochondrial structural damage of chloride cells after 96 h of continuous exposure.

Anthraquinone-2,6-disulfonate enhanced biodegradation of dibutyl phthalate: Reducing membrane damage and oxidative stress in bacterial degradation.

Plasticizer dibutyl phthalate (DBP) pollution has received more and more attention. In this study, a DBP degrading bacteria Enterobacter sp. DNB-S2 was found to suffer membrane damage and oxidative stress during DBP degradation.

Multi-component adsorption of Pb(II), Cd(II) and Ni(II) onto microwave-functionalized cellulose: Kinetics, isotherms, thermodynamics, mechanisms and application for electroplating wastewater purification.

Herein, microwave-functionalized cellulose derived from rice husk was cost-effectively prepared and employed for Pb(II), Cd(II) and Ni(II) elimination in mono- and multi-component systems. Benefiting from microwave irradiation, the functionalized process was achieved in 6.5 min and the resultant RH-X possessed remarkably high adsorption capacities of 295.

Efficient removal of atrazine by iron-modified biochar loaded Acinetobacter lwoffii DNS32.

In order to efficiently remove commonly used herbicide atrazine in farmland, an iron-modified biochar (FeMBC) was fabricated via chemical co-precipitation of Fe onto corn stalks biochar. The composites of FeMBC and Acinetobacter lwoffii DNS32 (bFeMBC) effectively accelerated the degradation rate of atrazine (100 mg L) in inorganic salt culture solution. TEM，XRD，XPS and FTIR were used to study the basic properties of the Materials.

Metabolism of diethyl phthalate (DEP) and identification of degradation intermediates by Pseudomonas sp. DNE-S1.

A Pseudomonas sp. DNE-S1 (GenBank accession number MF803832), able to degrade DEP in a wide range of acid-base conditions, was isolated from landfill soil. The growth kinetics of DNE-S1 on DEP followed the inhibition model.
