Adsorption Performance of Activated Carbon from Bamboo Charcoal with Coal Molding

【Objective】 To investigate the effects of proportioning between coal and biomass on the particle strength，apparent density，iodine adsorption value，methylene blue adsorption value，and pore structure  etc. of molded activated carbon preparation. 【Method】 In this study，bamboo charcoal with coal was used to prepare molded carbon，and granular activated carbon was prepared through steam activation. Representational means like scanning electron microscope，thermogravimet，nitrogen isothermal adsorption and desorption were used to analyze the physicochemical properties of the molded activated carbon made with bamboo charcoal and coal. 【Result】 The results show that introduction of bamboo charcoal will increase the adsorption values of  iodine and methylene blue of the molded activated carbon，but it will  reduce the strength and apparent density of the molded activated carbon，affecting its usage effects. 【Conclusion】 When the proportion of coal and bamboo charcoal was 1∶3，the indexes of adsorption performance and use strength both met the requirements，and the adsorption values of iodine  and  methylene blue were 934.7 mg·g^-1，165 mg·g^-1  respectively，and the strength was 86.4%，well meeting the regulations of national standard for drinking water，which has a good prospect for commercial application.
