Copper contaminated wastewater – An evaluation of bioremedial options

Abstract: The potential of papaya leaf powder and paddy straw powder for copper(II) removal was evaluated from aqueous solution via column and batch adsorption studies. Batch adsorption studies were performed to determine the contact time effects, biosorbent dosage, pH and initial concentration of metal ion on adsorption capacity. Results showed approximately 90% to 95% of copper removal using both the adsorbents from the solution. As the amount of biosorbent increases, the biosorption capacity also increases. Findings … Show more

“…So far, several technologies have been developed and utilized for Cu(II) removal from water and wastewater, and according to the reaction mechanism, the available studies classified these technologies as physicochemical (membrane separation, ion exchange, chemical precipitation, electrochemistry, adsorption) and biological (biosorption, bioprecipitation, biomineralization) [2,9,14,31] (Figure 1).…”

“…Copper, one of the most ubiquitous heavy metals, is a trace element essential for normal growth and cellular activities in all living organisms at low concentrations but it is toxic at high levels (Shamim 2018). Copper is one of the most used metallic substances in dye and paints production, petroleum refining, mining and metallurgy, fertilizer production, and electroplating industries (Tytla et al 2015;Varma and Misra 2016). Due to its bioaccumulative and nondegradable nature, copper contamination may greatly reduce biodiversity and harm human health.…”
