Abstract
In this article, we demonstrate the preparation of a new bionanocomposite by surface modification of malachite [Cu2(OH)2CO3] nanoparticles with bovine serum albumin (BSA). The conformation of protein in BSA−malachite nanocomposite has been analyzed by employing fluorescence and Fourier transform infrared (FT-IR) spectroscopic methods. The BSA molecule loses its tertiary and secondary conformation partially in BSA−malachite nanocomposite. For the first time, bare malachite nanoparticles and BSA−malachite nanocomposite have been used for the adsorption of a series of toxic and precious metal ions from single- and multicomponent aqueous solution. We report a reversal in adsorption behavior of selected metal ions upon surface modification of malachite nanoparticle with BSA. Among different metal ions studied here, the “harder” ions (according to HSAB principle), likely, Cu2+, Ni2+, Cr3+, and Zn2+, were preferably adsorbed on bare malachite surface but show less adsorption on BSA−malachite nanocomposite.
