Application of Bamboo Shoot Shell in Color Removal from Methylene Blue Solution

Abstract:

Biosorption of dyeing wastewater is most widely used method so far. The adsorption of methylene blue (MB) with bamboo shoot shell (BSS) as biosorbent was investigated. Orthogonal test was used to optimize the adsorption process, and adsorption capacity and color removal efficiency were used to judge the adsorptivity of BSS. Results showed that maximum adsorption capacity was 225.71 mg·g^-1, and color removal efficiency could achieve to 98.96% during the test. To obtain best adsorption capacity, the optimized conditions of temperature, initial concentration of dye, BSS dosage, pH value and adsorption time were 45 °C, 400 mg·L^-1, 10 mg/10 mL, 9.6 and 30 min, respectively. As to another target color removal efficiency, the best parameters were 100 mg·L^-1, 200 mg/10 mL, 11.5 and 120 min, respectively. The results reveal that the agricultural by-product BSS is an effective biosorbent.
