Identification of Kenaf(KB-6) Potential as Industrial Absorbent

The present study was performed using different particle size such as 75-150µm, 150-450µm and >600µm of a new variety of Kenaf (KB-6) to formulate low cost industrial higher absorbency. Required concentration of dye solutions were prepared by dissolving absorbent. Absorption method was applied for removing methylene blue (MB) and malachite green (MG) dyes from aqueous solution. The experiments were conducted in single absorbate system by batch techniques to determine the optimum condition for distilled water. The optimum condition of the effect of absorption were carried out at different absorbent dosage (0.2 g, 0.5 g and 1.0 g), temperature (3, 6.5 and 8) and pH (30 °C, 60 °C and 80 °C) respectively. The study was then carried out according to different treatments which were water bath treatment, alkaline treatment and acid treatment. The absorbent capacity of the treated kenaf core particles were compared with untreated kenaf core particles to find out the best possible option. Acid treatedparticles of bigger sizes show better performance for removal of methylene blue dye compared untreated and others treatments. The absorption capacity of malachite green dye was found maximum in water bath treated kenaf particles of small sizes. Hence, the new variety of kenaf (KB-6) can be used as an effective industrial absorbent to remove dyes from textile industries.
