TREATMENT OF TEXTILE WASTEWATER WITH CHERRY LAUREL LEAVES AND WASTE POTATO PEELS

Abstract

In this study, a research was carried out on the removal of dyestuff, which is a big problem in the textile industry. The adsorption method was used for the removal of Maxilon Yellow 4GL dyestuff. Cherry laurel leaf (Prunus laurocerasus) and waste potato peels were used as adsorbent, and the removal efficiency was determined as 76.64% at pH 7 and with 2 g adsorbent, 80% dyestuff removal efficiency was achieved in the specified conditions for cherry laurel leaves. For experiments in which waste potato peels were used as adsorbent, the optimum conditions were found as follows: Contact time: 60 minutes, adsorbent concentration of 0.75 grams and initial concentration of 25 mg/L. The Freundlich isotherm model was suitable for our study, since the regression number was found to be 0.999 for cherry laurel leaves and 0.995 for waste potato peels as a result of isotherm studies. According to the cost analysis, the materials supplied free of charge, due to mixing, the electricity cost for treatment (0.128 TL) and the chemical material cost is 17 TL, and it has been determined that these adsorbents are quite economical in dyestuff treatment. As a result, the fact that there is no study on the removal of cherry laurel leaves with the mentioned dyestuff in the literature shows that this study can be further developed.
