Abstract:

In many industries, dye compounds have been widely used to colorize substances, for example in textiles, papers, cottons, wool, and cosmetic products. Discharge of wastewater containing dye compounds into water sources will deplete the dissolved oxygen content in water and also inhibit sunlight from reaching to the water sources. Some of the dyes can release toxic compounds causing deterioration to ecosystem and human health. Methylene blue (MB) is one of the most widely used dyes among the dyeing agents, especially in textile industry. This study reports the feasibility of using lignocellulosic sources as agricultural residues (e.g. straws) and wood processing industry wastes (e.g. sawdust) to remove basic dyes like MB from water and wastewater. In particular, wheat straw, chickpea straw, lentil straw, Norway Spruce (Picea Abies) sawdust, algae and cork have been used as absorbents for MB, which is one of the most widely, used dyes in research (as a reference pollutant) and in industry. The purpose of this study was to provide comparable results on the adsorptivity of a wide range of potentially low­cost adsorbents for dyes removal.
