Microwave-assisted KOH activated lignite semi-coke for treatment of biologically treated wastewater from pulp and paper mill
Original language description
In view of the urgent need to treat biologically treated wastewater from pulp and paper mill (BTW) and the high cost of commercial activated carbon, microwave-assisted KOH activated lignite semi-coke (MLSC) was prepared for adsorption of BTW. Through the research, the best preparation conditions of MLSC are obtained (ratio of KOH/lignite semi-coke (LSC) = 1, radiation time 10 min, and microwave power 700 W). In order to further study the effect of microwave power, three kinds of MLSC were prepared under the conditions of 600 W (MLSC-600), 700 W (MLSC-700) and 800 W (MLSC-800), and a series of characterizations were performed. The research of coupled thermogravimetric and mass spectrometer system showed that KOH impregnated LSC produced hydrogen during pyrolysis, which proved that activation reaction took place between KOH and LSC. And pore characteristics study found that most of the pore size of MLSC was less than 0,7 nm, and MLSC 700 had finer micropores (0,6 nm-0,65 nm). The adsorption experiment
