The Current State-Of-Art of Copper Removal from Wastewater: A Review

Abstract

Copper is one of the chemical elements that is widely used in various sectors nowadays together with the development of civilization especially in agricultural and industrial sectors. Copper is also considered as one of the heavy metals that is commonly present in wastewater. This preliminary study conducted is mainly focused on the techniques of removal of copper in wastewater. There are a variety of approaches for treating industrial effluent contaminated with heavy metals such as copper. Copper separation can be accomplished using a variety of technologies, each of which has advantages that vary depending on the application. Chemical removal techniques that are commonly used for copper removal are adsorption, cementation, membrane filtration, electrochemical method, and photocatalysis. This study compares the fundamentals and performances of the treatment techniques in addition to the future perspective of copper removal in detail. The study highlights the present research in terms of its strengths and shortcomings, pointing out deficiencies that need to be addressed in future studies, pointing to future research prospects.

Analysis of Heavy Metals Concentration and Pollution Index on Water Quality in Labuan Beach Fishery Port Area, Banten

“…Berdasarkan kurva kalibrasi diperoleh persamaan regresi linear y=0,1585x+0,0004 yang selanjutnya digunakan untuk menghitung konsentrasi Cu di perairan. terkontaminasi logam Cu sebaiknya diolah sebelum dibuang ke lingkungan ( Hamid et al, 2022). Adanya kandungan logam Cu pada perairan di sekitar kawasan PPP Labuan dapat disebabkan oleh adanya beberapa aktivitas seperti wisata pantai dan kuliner, pasar ikan, serta jalur kapal yang dapat mempengaruhi kondisi perairan.…”

Kinetic and Isotherm Studies for Cu2+ and Cs+ Uptake with Mono- and Bimetallic FeO(OH)-MnOx-Clinoptilolite

“…Among the recommended techniques like chemical precipitation, ion exchange, membrane filtration, coagulation-flocculation and adsorption, adsorption is undoubtedly one of the most economically viable and effective methods in water technology [8][9][10][11][12][13][14][15]. Adsorption is also considered one of the most suitable methods for final water purification, owing to its simplicity and the availability of various natural or commercial adsorption materials [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Over the last decade, nanomaterials-based zeolite-type mesoporous adsorbents have garnered attention in the scientific community for removing hazardous metal pollutants, including radionuclides.…”

“…In the case of an ion exchange separation of Cs, inorganic ion exchangers are found to be superior over organic ion exchangers due to their thermal stability, resistance to ionising radiation and good compatibility with final waste forms. Therefore, several clay minerals, including montmorillonite, illite and others, have also been applied for the removal of radioactive contaminants [8][9][10][19][20][21][22]28,31]. While natural zeolites have traditionally been used for removing Cs-137 from low-and intermediate-level radioactive waste effluents, a drawback lies in the competitive interactions of other monovalent cations, particularly Na and K in waste effluents, which can considerably lower Cs adsorption [8,9,22,31].…”

Optimizing copper removal from synthetic water using electrocoagulation and response surface methodology

“…Each treatment technique has benefits but also shows some disadvantages. For example, adsorption, although very efficient and inexpensive, limits the concentration of copper ions, while membrane filtration, although clean, can be expensive; likewise, photocatalysis is simple and environmentally friendly, but time-consuming (Ab Hamid et al, 2022) Electrocoagulation has been widely used to remove heavy metals, including Cu, from industrial effluent (Akbal and Camcı, 2010;Rincón and La Motta, 2014). Recently, EC has attracted more attention due to the following advantages: high-quality effluents, low energy consumption, low-dissolved solids, and low sludge formation (Chen, 2004;Moradi et al, 2021).…”

“…EC removes copper ions from water using electrical current and is based on the generation of coagulant in situ by dissolving a metal anode made of Al, Fe, or a hybrid Al/Fe electrode. The anode generates metal ions, while the cathode produces hydrogen gas, which can help drive the agglomerate particles out of the water (Ab Hamid et al, 2022). The main reactions occurring in the EC process for iron electrodes are given in Equations 1-5.…”
