Abstract

This study was aimed to investigate the possibility of using MAGNESIUM HYDROXIDE as an alternative for SODIUM HYDROXIDE in DEINKING of newsprint and magazine mixture. The OLD NEWSPRINT and magazine mixture (ONP/OMG -70/30) was treated by MAGNESIUM HYDROXIDE at three levels: 1, 1.5 and 2 percent (based on oven dried pulp weight), for 20 min. Optical and mechanical properties and effluent COD load were compared to those of control and NaOH treated samples. Results showed that effluent COD load of Mg (OH)2 chemical treatments was less than that of NaOH treatment. Also, results indicated that 1.5% Mg (OH)2 treatment, which was done in pulp DEINKING, had better results compared to other treatments and also NaOH treatment. In the other words, it is the best treatment for both optical and mechanical properties. Thus, substitution of SODIUM HYDROXIDE by MAGNESIUM HYDROXIDE for DEINKING of newsprint and magazine wastepaper suggested.
