Ability of Pycnoporus Sanguineus to Remove Copper Ions from Aqueous Solution

Abstract

The equilibrium sorption capacity of a macro-fungi, Pycnoporus sanguineus biomass was studied using a single-metal system comprising copper ions. The rate and extent for the removal of copper were subjected to environmental parameters such as pH, biomass loading, temperature, and contact time. Results showed that the uptake of copper increased as the pH increased. However, as the biomass loading increased, the amount of metal uptake decreased. Instead, temperature does not have a significant effect on the metal uptake, especially between 30 to 40 degrees C. A maximum adsorption of copper ions was also observed within 15 minutes of reaction time for the entire sample tested. Furthermore, pre-treatment with sodium bicarbonate and boiling water significantly improved the sorption capacity of copper by Pycnoporus sanguineus.

Biosorption of copper (II) onto immobilized cells of Pycnoporus sanguineus from aqueous solution: Equilibrium and kinetic studies

“…However, the Cu (II) uptake onto the biosorbents decreased as the loading increased. According to the previous work, higher biosorbent loading could produce a 'screening' effect on the cell wall, protecting the binding sites, thus resulting in lower Cu (II) uptake [1,54]. Fig.…”

“…Though dead cells of P. sanguineus are also reported as a potential biosorbent for Pb (II), Cu (II) and Cd (II), no studies have reported on Cu (II) biosorption by immobilized live cells system of P. sanguineus [1]. In industrial operation, immobilization is one of the methods used to overcome the incorporating free suspended cells in wastewater treatment.…”

“…Copper (II) is one of the toxic compounds commonly found in an electroplating industrial effluents [1]. Disposal of industrial effluents containing copper (II) ions into natural water beyond limits may harm the living organisms including human [1,2]. Conventional methods used to remove metal ions from industrial wastewater include chemical precipitation, electrochemical treatment, ion exchange process, membrane separation and evaporation [2,3].…”

Synthesis of oak gall tannin-immobilized hexagonal mesoporous silicate (OGT-HMS) as a new super adsorbent for the removal of anionic dye from aqueous solution

“…They reported that high concentration of the biosorbent could exhibit a screening effect in the outer layer of the cell and would hence protect the binding sites from the copper ions uptake. Therefore, the copper removal capacity would be decreased accordingly [44,45]. In this paper, the measurements were carried out in the presence of 0.01, 0.015, 0.02, 0.025, 0.05, 0.075, 0.1, and 0.15 g of OGT-HMS adsorbent with the initial dye concentration of 40 ppm, pH of 2.0, and temperature of 20˚C.…”
