Abstract

Abstract

Using graphene as the adsorbent, and reactive black KN-B as the target pollutant to simulate dye wastewater, the influencing factors of adsorption treatment of reactive black KN-B simulated dye wastewater and the adsorption behavior of reactive black KN-B on graphene surface were investigated. The results showed that under the optimum reaction condition of adding 2 g/L of graphene in 50 mL solution, pH value was 5.0, oscillating rate was 100 r/min, oscillating at 40 ℃ for 60 min, the removal rate of absorption 50 mg/L reactive black KN-B dye wastewater could reach 94%. It was found that Langmuir adsorption isotherm and quasi-second-order kinetics could be used to describe the adsorption behavior of reactive black KN-B on graphene surface, and then this course could be defined as monolayer chemisorption.
