Agriculture waste from banana peel as low cost adsorbent in treating methylene blue from batik textile waste water effluents

Abstract

Abstract Batik industrial textile waste water effluent if improperly disposed to the catchment can cause the water pollution that will endanger human health and the environment. The contaminants discharge in the dye processing causes the water pollution. Banana peel is a potential agriculture waste that can be used to reduce the concentration of color from synthetic dye effluents. This study is aim to determine the potential of banana peel as agricultural waste adsorbent for Methylene Blue (MB) removal at different contact time (15minutes, 30 minutes, 45 minutes, 90 minutes, 120 minutes, 150 minutes, and 180 minutes) and different adsorbent dosage (0.05, 0.1, 0.15, 0.2, 0.25, 0.3, and 0.4 gram) and to develop kinetic model for Methylene Blue (MB) removal. The experiments were conducted at room temperature using batch study. As the banana peel dosage is added from 0.05 g to 0.4 g in 100 ml of Methylene Blue solution, the percentage of MB solution removal also increase from 34.69 % to 86.88 %, indeed due to the increase in phenolic compounds adsorption rates. The adsorption process reached the optimum contact time at 150 minutes with MB solution removal of 86.22 %. The kinetic data obtained specified that the data follow closely the pseudo-second-order. It is concluded that banana peel can act effectively as natural adsorbent in treating Methylene Blue (MB) from batik textile wastewater effluents.
