Adsorption Removal of Phosphate from Rural Domestic Sewage by Ca-Modified Biochar Derived from Waste Eggshell and Sawdust

Water, Journal Year: 2023, Volume and Issue: 15(17), P. 3087 - 3087

Published: Aug. 28, 2023

In recent years, in order to improve the rural living environment, domestic sewage treatment has received more and attention China. However, standard compliance rate of total phosphorus (TP) after is very low, TP become main pollutant that prevents facilities from meeting water pollutants discharge standards. this study, prepare calcium-modified biochar composites (E-BC) by one-step pyrolysis, waste eggshell (E) was employed as a calcium source pine sawdust (BC) carbon source. The E-BC produced were effective adsorbing phosphate (P) aqueous solutions broad pH range 3–11, with good adsorption selectivity. E-BC’s capacity for P increased pyrolysis temperature 700 °C 900 °C, which attributed higher specific surface area oxide content at temperatures. sample, made (filtered through 100 mesh sieves) mass ratio 2:1 had maximum 301 mg/g. Langmuir model pseudo second-order best describing process, predominant sorption mechanism chemisorption reaction or hydroxide create hydroxyapatite. can effectively remove sewage. removal ranges 95.3 99.5%. After treatment, meets second-grade (TP < 3 mg/L) even first-grade 2 mg/L). This study provides an experimental basis efficient using adsorbent materials suggests possible applications

Superior Removal of Vanadium(V) from Simulated Groundwater with a Fe-Based Metal–Organic Framework Immobilized on Cotton Fibers

Langmuir, Journal Year: 2023, Volume and Issue: 39(47), P. 16863 - 16872

Published: Nov. 14, 2023

A suitable adsorbent is essential in the process of removing hazardous vanadium(V) from actual groundwater. In this work, MIL-88A(Fe)/cotton (MC) was employed to eliminate V(V) simulated vanadium-contaminated The findings demonstrated that MC exhibited an exceptional performance V(V), displaying a maximum adsorption capacity 218.71 mg g-1. exhibits great promise as for elimination extensive pH range spanning 3 11. Even presence high levels competing ions such Cl-, NO3-, and SO42-, remarkable specificity adsorbing V(V). results column experiments co-occurring influence tests indicate potential candidate effectively treating effluent could meet vanadium content restriction 50 μg L-1 required China's drinking water sources. Regeneration can be performed easily without experiencing significant loss. obtained research promising mitigating pollution.

Removal of Dye from Aqueous Solution Using Ectodermis of Prickly Pear Fruits-Based Bioadsorbent

Sustainability, Journal Year: 2023, Volume and Issue: 15(6), P. 4700 - 4700

Published: March 7, 2023

Billions of grams ectodermic fruits, such as prickly pear are removed and thrown waste worldwide. In this study, an inexpensive approach was used to successfully transform the agricultural fruit peels (PPFP) into a new adsorbent remove dye (PTZIDM). The PPFP revealed porous structure fair surface area. It characterized evaluated using scanning electron microscope (SEM), Fourier infrared spectroscopy (FTIR), area measurements (BET). effectiveness PPFP’s adsorption assessed in relation pH, dose, contact time, initial concentration. kinetics isotherm characteristics were investigated. More than 95% removal efficiency obtained within 60 min at dose 0.1 g for concentration 1 × 10−5 M pH 3. pseudo-second-order models Langmuir excellent explaining characteristic adsorption. This work offers rapid simple method efficiently converting biomass it pollutants.
