The rose shaped MoS2 was synthesized by hydrothermal method and its adsorption photocatalytic synergistic treatment performance on potassium butyl xanthate was investigated.The results showed that rose shaped MoS2 with photocatalytic and adsorption properties was successfully prepared.When pH=7,the amount of MoS2 was 25 mg,and the adsorption time was 30 minutes,the maximum adsorption capacity of MoS2 for potassium butyl xanthate can reach 110.93 mg·g-1.Under 300 W xenon lamp irradiation for 30 minutes,the degradation efficiency of potassium butyl xanthate on MoS2 was 81.99％.Through the synergistic effect of photocatalytic degradation-adsorption,potassium butyl xanthate can be almost com-pletely removed within 40 minutes(degradation efficiency of 99.89％).After 5 cycles,the synergistic removal efficiency of potassium butyl xanthate by MoS2 can still reach over 95％.This study opens up a new method for MoS2 application in the treatment of xanthate containing wastewater.
