Removal of Congo red Dye from a Synthetic Wastewater Using Parthenium Carbon as a Bio-Adsorbent- An Environmental Sustainability

In this study analysis were conducted for synthetically prepared Congo red dye. Activated parthenium carbon derived from Parthenium hysterophorous weed employed as an adsorbent. Physical activated carbon (PAC) & chemical activated carbon (CAC) both were used for experiential under batch studies. Dye molarity 1500 mg/l, other parameters like carbon dose, pH, & time in contact were examined. Optimum adsorbent of 3g/50ml, pH 8.5, time in contact of 60 min were found effective. Column studies were carried to examine the role of dye starting concentration, rate of flow & bed height on process of sorption. The optimum pH and Flow rate was 8.5 and 10 ml/min respectively. Modern techniques like IOT was used in getting real time data of parameters. SEM, FTIR were recorded which shows good surface morphology, group of functional elements (C=O, C-O, O-H). Parthenium weed can be considered as ideal material for dye sorption, the efficiency of sorption studies observed 95-99%. This model best fits for Freundlich isotherm adsorbent is heterogeneous; overall process is economical and sustainable.
