Preparation and characterization of ethylenediamine modified glycidyl methacrylate-grafted nonwoven cotton fabric adsorbent
Abstract
In this study, plasma-initiated graft polymerization of glycidyl methacrylate (GMA) onto nonwoven cotton fabric (NCF) and its modification with ethylenediamine (EDA) was performed. To determine the optimum conditions for plasma treatment, a comprehensive analysis of different parameters such as plasma power, applied pressure, applied plasma gas, and exposure time were conducted using both air- and Ar-plasma. The concentration of radicals generated on the NCF surface after plasma treatment was examined using ESR spectroscopy. The effects of plasma pretreatment conditions, namely GMA concentration, grafting temperature, and grafting time were investigated. Plasma treated NCF has been grafted with GMA (GMA-g-NCF) was functionalized with ethylenediamine (EDA-GMA-g-NCF) to develop an efficient arsenic adsorbent. NCF, GMA-g-NCF and EDA-GMA-g-NCF samples were characterized by using FTIR, SEM, EDX, XPS, elemental analysis, TGA, and contact angle.
