Enhanced soil P immobilization and microbial biomass P by application of biochar modified with eggshell

Journal of Environmental Management, Journal Year: 2023, Volume and Issue: 345, P. 118568 - 118568

Published: July 6, 2023

Phosphate fertilizers have been excessively applied in agricultural production, bringing the risk of phosphorus (P) loss to nearby river systems and low utilization efficiency. In this study, eggshell-modified biochars prepared by pyrolysis eggshell corn straw or pomelo peel were soil for enhancing P immobilization utilization. The structure properties modified before after adsorption analyzed using Brunauer-Emmett-Teller (BET) nitrogen method, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), photoelectron (XPS), scanning electron microscope (SEM). biochar performed an excellent performance (up 200 mg/g), which was well described Langmuir model (R2 > 0.969), showing monolayer chemical with homogenous surface. Ca(OH)2 appeared on surface changed Ca5(PO4)3(OH) CaHPO4(H2O)2 adsorption. release immobilized increased decreased pH. addition, pot experiments soybean indicated that combined application fertilizer significantly content microbial biomass soil, raising from 4.18 mg/kg (control group) 51.6–61.8 (treatment group), plants height 13.8–26.7%. Column leaching showed concentration leachate 97.9% application. This research provides a new perspective could serve as potential amendment

Catalytic reactivity performance is a significant challenge for catalytic wet peroxide oxidation (CWPO) technologies. Copper-impregnated eggshells (x%Cu@ES) were tested as potential new low-cost catalyst to improve the CWPO process toxic dyes Congo Red (CR) and Crystal Violet (CV). The structure, morphology, chemical composition of x%Cu@ES analyzed using FTIR, XRD, SEM-EDX. Oxidative degradation both enhanced by presence x%Cu@ES, which generates hydroxyl radicals in reaction medium after contact with hydrogen peroxide. Decolorization rates according Box Behnken design are order 99.88 % 99.99 CR CV respectively under optimum conditions 1 copper content, 0.074 M H2O2 concentration, 60 mg L−1 dye 2 g dose.

Environmental Applications of Biobased Polydopamine-β-Cyclodextrin-Epichlorohydrin Supramolecular Hydrogel with Tuneable Swelling and Selective Adsorption Behaviors

ACS Applied Polymer Materials, Journal Year: 2024, Volume and Issue: 6(6), P. 3493 - 3506

Published: March 8, 2024

Supramolecular hydrogels have been extensively studied for environmental applications owing to their biocompatible, nontoxic, and cost-effective properties. Herein, a polydopamine-β-cyclodextrin-epichlorohydrin (PDA-β-CD-EP) supramolecular hydrogel was facilely prepared through one-pot polymerization using molar ratio of dopamine (DA)/β-cyclodextrin (β-CD)/epichlorohydrin (EP) 1/2/50. Compared with other hydrogels, the can selectively adsorb malachite green from mixed dyes. The structure, surface morphology, thermostability PDA-β-CD-EP were illustrated by FT-IR, SEM–EDX, TGA-DTG, respectively. Interestingly, PDA-β-CD-EP-2 exhibited excellent pH-responsive swelling behavior. influences pH, adsorption time, dosage, initial concentration systematically studied. Under optimal conditions, maximum capacity 652.1 mg/g MG according Langmuir fitting results, much higher than those adsorbents. More importantly, possessed good reproducibility, reusability, biodegradability. Besides, selective mechanism proposed proved, such as hole size shape effect, electrostatic force, host–guest interaction. Overall, this study could provide method prepare biosorbent wastewater remediation.
