Effect of pH and Concentration on Biosorption Malachite Green and Rhodamine B Dyes using Banana Peel (Musa balbisiana Colla) as Biosorbent

Abstract

All Biosorption of Malachite green and Rhodamine B dyes using banana peel (Musa balbisiana Colla) as a biosorbent has been carried out. The purpose of this study was to determine the effect of pH and concentration for biosorption of Malachite green and Rhodamine B by banana peel biosorbent (Musa balbisiana Colla). The method used is the batch method. The maximum wavelength of Malachite green is 618 nm and Rhodamine B 555 nm measured by the UV-Vis Spectrophotometer. The results showed that the optimum conditions for Malachite green adsorption occurred at pH 3, a concentration of 100 ppm 8,0662 mg/g. The optimum conditions for Rhodamine B adsorption occurred at pH 3, a concentration of 120 ppm 16,6614 mg/g. The adsorption isotherm of Malachite green with banana peel (Musa balbisiana Colla) biosorbent tends to follow the Freundlich isotherm with a determinant coefficient (R2) of 0.9996 and Rhodamine B 0,9884.

Synthesis of materials from agricultural wastes combined with Fe3O4 for methylene blue adsorption and application to treat organic pollutants in water samples

“…This research aims to achieve at least two objectives: first, to create potential adsorbent materials for organic dye adsorption from lowcost agricultural waste available in nature, and second, to contribute to reducing environmental pollution caused by these waste products. Currently, many studies have been published on the use of agricultural waste as a precursor for synthesizing adsorbent materials for organic dyes adsorption, such as orange peels, 2,3 grapefruit peel, [4][5][6][7] coffee grounds, [8][9][10] banana peels, [11][12][13][14][15] corn waste, [16][17][18][19][20] peanut shells, [21][22][23] durian waste, [24][25][26][27] dragon fruit peels, [28][29][30] etc. Dragon fruit peels have been attracting attention for synthesizing adsorbent materials for organic dyes adsorption due to the presence of compounds such as phenolic compounds, betalains, betacyanins, and other functional groups like C═C, C═O, OH, and NH.…”

Adsorption of Malachite Green Using Activated Carbon from Mangosteen Peel: Optimization Using Box-Behnken Design

“…In the textile coloring process, as much as 5%-15% of the dyes used in the fabric coloring process were disposed of as liquid waste [3]. Many studies have been carried out to convert or decompose dye liquid waste, such as biological degradation [2], phytoremediation [3], coagulation-flocculation [4], reverse osmosis [5], and adsorption [6]. Adsorption is a popular method because it is relatively cheap, efficient, a simple process, and easy to apply even on a small scale [7].…”
