International Journal of Environmental Research and Public Health, Journal Year: 2023, Volume and Issue: 20(5), P. 3885 - 3885

Published: Feb. 22, 2023

Copper pollution of the world’s water resources is becoming increasingly serious and poses a threat to human health aquatic ecosystems. With reported copper concentrations in wastewater ranging from approximately 2.5 mg/L 10,000 mg/L, summary remediation techniques for different contamination scenarios essential. Therefore, it important develop low-cost, feasible, sustainable removal technologies. Various methods heavy metals have been extensively studied recent years. This paper reviews current used treat Cu(II)-containing evaluates these technologies their effects. These include membrane separation, ion exchange, chemical precipitation, electrochemistry, adsorption, biotechnology. Thus, this paper, we review efforts technological advances made so far pursuit more efficient recovery Cu(II) industrial compare advantages disadvantages each technology terms research prospects, technical bottlenecks, application scenarios. Meanwhile, study points out that achieving low risk effluent through coupling focus future research.

Adaptable Biomolecule-Interactive Dual Colorimetric Chemosensor for Cu²⁺ and Pd²⁺: Insight from Crystal Structure, Photophysical Investigations, Real-Time Sampling, and Molecular Logic Circuits

Crystal Growth & Design, Journal Year: 2024, Volume and Issue: 24(3), P. 1051 - 1067

Considering the crisis of single probes for simultaneous colorimetric detection both Cu2+ and Pd2+ metal ions, which are toxic to living organisms even in trace amounts, this communication, we report facile synthesis characterization, including single-crystal X-ray diffraction (SCXRD), a molecular probe (E)-3-((2-(methylthio)phenyl)diazenyl)-[1,1′-biphenyl]-4-ol (TABH). TABH is bioactive avidly interacts with biomolecules such as BSA protein CT DNA, evidenced by spectrofluorometric photometric tests. The also proficient selective swift sensing ions ACN/H2O (4/1 v/v, pH = 7.2) medium over other ions. sensor's ability selectively bind analytes demonstrated noticeable color shift from yellow reddish brown violet Pd2+, clearly visible human eye. A detailed investigation recognition mechanism using Job's plot, 1H nuclear magnetic resonance (NMR), infrared (IR) analysis, electrospray ionization (ESI) mass density functional theory (DFT) calculations confirmed 1:1 binding stoichiometry Furthermore, chemosensor exhibits strong association affinity (7.61 × 104 1.42 105 M–1 respectively) low limit (54.8 5.32 nM respectively). Binding data absorption studies revealed that had higher than Cu2+. This makes it simple replace [TAB-Cu2+] complex, increasing Pd2+'s differential selectivity reversible addition ethylenediaminetetraacetic acid (EDTA) triphenylphosphine (PPh3), whereas exclusively presence PPh3 only. activities were investigated logic operations AND, OR, NOT gates. In addition, chemoprobe proved be effective identifying actual water samples. It was then converted into test strips, creating portable device on-site analysis testing.

Treatment of electroplating wastewater using electrocoagulation and integrated membrane

Water Science & Technology, Journal Year: 2024, Volume and Issue: 89(9), P. 2538 - 2557

Published: April 26, 2024

ABSTRACT Electroplating wastewater contains heavy metal ions and organic matter. These contaminants not only endanger the environment but also pose risks to human health. Despite development of various treatment processes such as chemical precipitation MBR, electrocoagulation (EC) ceramic membrane (CM), coagulation ultrafiltration (UF) reverse osmosis (RO), CM RO. methods are effective for low concentrations metals struggle with high concentrations. To address challenge treating electroplating content, this study focuses on from Dongfang Aviation Machinery Processing Plant. It introduces an EC integrated (IM) process wastewater. The IM comprises microfiltration (MF) membrane, nanofiltration (NF) RO membrane. Results indicated that under specific conditions, a pH 8, current density 5 A/dm2, electrode plate spacing 2 cm, 35 min electrolysis time, influent 10 IM, removal rates Zn2+, Cu2+, Ni2+, TCr in exceeded 99%. oxygen demand (COD), suspended solids (SS), total phosphorus (TP), nitrogen (TN), petroleum exceed 97%. Following continuous cleaning process, flux can consistently recover over 94.3%.
