Treatment of pyridine bearing wastewater using activated carbon

摘要

Paper examines the adsorption of toxic and odorous pyridine from water onto activated carbon in batch and column systems. Batch studies reveal that the removal of pyridine onto activated carbon increases with the increase in initial concentration of pyridine. At an initial concentration of 200 mg/l, 96.4 per cent removal of pyridine was obtained. Equilibrium adsorption data could be represented by both the Freundlich and Langmuir model. Kinetic modelling of removal of pyridine was done using Lagergren first order rate expression. Intraparticle diffusion is found to be rate controlling. Column test data are found to fit BDST model.
