Abstract

Imperata grass microcrystalline cellulose modified with Cu nanoparticles is one of the alternative adsorbents for the reduction of the concentration of methylene blue (MB) dye. The effectiveness of this developed adsorbent in the adsorption process of MB dye was studied. Cu nanoparticles were employed to modify the synthesized cellulose microcrystalline imperata grass. The modified Cu-cellulose adsorbent was successfully produced with brown color and Fourier Transform Infra-Red (FT-IR) identified the presence of OH, CH, and CO peaks. X-ray diffraction (XRD) analysis also confirmed that the produced adsorbent was in microcrystalline phase with a crystal size of 4.402 nm The microcrystalline cellulose-Cu nanoparticles used showed potential as an MB adsorbent, where the MB removal percentage (% A) was 59.574%.

Abstract

One of the heavy metals contained in the textile industry wastewater is chromium (Cr). Chromium hexavalent ions (Cr6+) are highly toxic and its accumulation in the human body will cause various negative impacts. This study aimed to determine the characteristics of silica synthesized by the sol-gel method to gain homogeneity and high purity. Synthesized silica was calcined at 700°C for 4 hours and its performance to adsorb Cr(VI) ions  in textile wastewater was investigated. The presence of -OH group from silanol (–Si-OH) was appeared at wavenumber 3367.70 cm-1, meanwhile siloxane functional groups were recorded at 1056.99 cm-1 and 784.38 cm-1 due to the O-Si-O asymmetric stretching and Si-O bending vibration. Optimum conditions of silica to adsorb Cr(VI) ions took place at pH 2 and contact time of 90 minutes by adsorption efficiency of 75,65% and followed the Freundlich isotherm.
