Abstract
This work aims to extraction of valuable cellulosic biomaterials namely; carboxymethyl cellulose (CMC) and carbon quantum dots (CQDs) from agriculture cellulosic waste (agro wastes) via economically and ecofriendly single-step method. CMC and CQDs were then mixed with nylon-6 to get suitable composite solutions that electro-spun into nano-fibers (NFs) by using nozzle-less electrospinneret. The obtained functional NFs were applied in adsorption and capturing of dye molecules and heavy metal cation from the contaminated water. The morphological structure of the obtained NFs was investigated by SEM. Chemical and thermal properties of the obtained NFs were studied by FT IR, T GA, and DSC. Depending on their composition, the capacities of the prepared NFs to capture Cr+6 as well as to adsorb cationic dye were examined. Results of this study show the higher efficiency of the prepared cellulosic biomaterial/nylon-6 NFs to adsorb and capture dye molecules and Cr+6 reached to about 86% and 93%; respectively.
