Copper Lead and Cadmium Removal from Aqueous Solution Using Banana Peels

Abstract

In experiments, banana peels have been utilized to remove copper, cadmium, as well as lead ions from single, binary, and ternary aqueous solutions. Batch biosorption research to look at the biosorption ability, agitation speed, pH value, and concentrations of metal ions. The biosorption method revealed that banana peels were an efficient biosorbent about the removal of metal ions at a beginning concentration of 50 milligrams per liter. Atomic Absorption A spectrophotometer was used to measure the residual concentrations of Pb (II), Cd (II), and Cu (II). The optimal pH for the removal of Cd (II) and Pb (II) ions had been found to be 5, whereas the optimal pH for the removal of Cu (II) ions had been found to be 6. Studies of zeta potential found that at pH 5, the negative locations on banana peels had the highest zeta potential. Fourier transition infrared spectrometric analysis has been utilized to figure out the impact of functional clusters in banana peels. According to the data, biosorption is a complicated process that depends on the numbers and kinds of active clusters. This procedure involves sulfonic, carboxylic, hydroxylic, aromatic, and amino groups. Because of its strong attraction for banana peels, Pb(II) induced a higher alteration in the functional clusters of banana peels. Comparing the binary system and ternary system to a single system, the removal efficiency of metals ions was lower. For a singular system, the order for removing metal ions had been Pb > Cd > Cu, but for binary and ternary systems, the order had been Pb > Cu > Cd. Also, the results of the experiments showed that this a biosorption of Cu(II),Pb(II), as well as Cd(II) ions matched both a Langmuir isotherms of a single system beside the extended Langmuir isotherms across binary system & ternary system. Kinetic experiments have revealed that the pseudo-second-order model is superior to the pseudo-first-order model.
