Abstract:
Cotton is a material of significant importance because of its composition and production volume. This production volume has huge amounts of cotton waste, including medical cotton waste. These wastes can become a considerable source of recycled biomass via pretreatment, instead of treated as common waste and end up in the land-field. Acid hydrolysis was chosen as pretreatment method to sterilize cotton waste and convert it into recycled biomass. Dyes, like Methylene Blue (MB), are common pollutants of water resources and their removal occurs via several treatment methods, among them adsorption. Adsorption is an effective method which is commonly used. The growing demand for efficient and low-cost treatment methods as well as the importance of adsorption has brought attention to low-cost adsorbents. The purpose of this study is to discover whether acid hydrolysis pretreatment makes medical cotton waste an efficient material regarding basic dyes removal from substitute wastewater. A 3.75 L batch reactor was used to achieve acid hydrolysis. The conditions applied were a result of a design of experiments (DoE) using time, temperature, and acid concentration as parameters. The effect of the pretreatment conditions on MB adsorption, was investigated. The applicability of pseudo-first order adsorption kinetic model was studied.
