Abstract
This paper is intended to investigate the effect of the binary composite microspheres pre-pared by sodium alginate coated fly ash based zeolite on the adsorption properties of dye wastewater.The study is performed by preparing 3ZFA-SA composite microspheres by blending fly ash-based zeolite(ZFA)prepared by alkali meltwater hydrothermal method with sodium alginate(SA);simulating the single dye wastewater by using methylene blue(MB)solution to study adsorption properties;and charac-terizing and analyzing this adsorption properties by SEM,XRD and FTIR.The results show that the ad-sorption performance of composite microspheres is lower than that of fly ash based zeolite,but still much higher than that of original fly ash,and easy to recover,and it still has high adsorption performance after multiple cycles,which has the potential to be recycled;At normal temperature,given the optimum exper-imental condition:the initial concentration of MB solution 150 mg/L,dosage of 3ZFA-SA 3 g/L,and pH 8,the saturation state can appear by adsorption for 90 min,and the maximum adsorption capacity and removal rate are 63.79 mg/g and 91.86%.关键词
