Groundwater contamination by heavy metals (HMs) released weathering and mineral dissolution of granite, gneisses, ultramafic, basaltic rock composition causes human health concerns worldwide. This paper evaluated the concentrations physicochemical variables groundwater around enriched chromite mines Malakand, Pakistan, with particular emphasis on water quality, hydro-geochemistry, spatial distribution, geochemical speciation, impacts. To better understand hydrogeochemical profile HMs enrichment, samples were collected from mining region (n = 35), non-mining 20), 5) then analyzed using ICPMS (Agilent 7500 ICPMS). The ranges in mining, non-mining, 0.02-4.5, 0.02-2.3, 5.8-6.0 mg/L for CR, 0.4-3.8, 0.05-3.6, 3.2-5.8 Ni, 0.05-0.8, 0.6-1.2 Mn. Geochemical speciation such as OH-, H+, Cr+2, Cr+3, Cr+6, Ni+2, Mn+2, Mn+3 was assessed atomic fluorescence spectrometry (AFS). determined mobilization, reactivity, toxicity complex systems. facies showed 45% CaHCO3, 30% NaHCO3, 23.4% NaCl, 1.6% Ca-Mg-Cl types. noncarcinogenic carcinogenic risk outlined via hazard quotient (HQ) total indices (THI) following order: Ni > Cr Thus, HHRA model suggested that children are more vulnerable to than adults. Hierarchical agglomerative cluster analysis (HACA) three distinct clusters, namely least, moderately, severely polluted which severity be 66.67% overall. PCAMLR PMF receptor geogenic (minerals prospects), anthropogenic (industrial waste practices), mixed (geogenic anthropogenic) sources contamination. phases saturation undersaturation. Nemerow's pollution index (NPI) values unsuitability domestic purposes. EC, turbidity, PO4-3, Na+, Mg+2, Ca+2, Cr, Mn exceeded guidelines World Health Organization (WHO). non-carcinogenic impacts is extremely unfit drinking, agriculture, demands. Therefore, wells need remedial measures. overcome enrichment sources, sustainable management plans needed reduce risks ensure safety.

Advancements in application of modified biochar as a green and low-cost adsorbent for wastewater remediation from organic dyes

Royal Society Open Science, Journal Year: 2024, Volume and Issue: 11(5)

Published: May 1, 2024

Synthetic organic dyes, which are resistant to biodegradation, pose a notable health risk, potentially leading cancer and respiratory infections. Researchers have addressed this concern by exploring physicochemical methods remove dyes from wastewater. A particularly promising solution involves modified biochar adsorbents, demonstrate high efficiency in dye removal. Biochar, charcoal-like material derived biomass pyrolysis, offers advantages such as low cost, eco-friendliness, reusability. Beyond its role sustainable soil remediation, proves effective removing wastewater after undergoing physical or chemical modification. Acid–base activation metal–heteroatom impregnation enhances biochar's adsorption capacity. This comprehensive review examines the attributes of biochar, common for production modification, impacts raw materials, pyrolysis temperature, heating rate residence time. It further elucidates mechanism removal assessing factors influencing efficiency, including feedstock, pH, particle size, initial concentration, dosage reaction explores challenges, opportunities, reusability regeneration treating also discusses recent advances using adsorption-based biochar. The ultimately advocates enhancing performance through post-modification.
