Abstract

Tea waste is a low-cost alternative material for making adsorbent to remove methylene blue from synthetic dye wastewater perpetually. Optimization of the adsorbent process utilized Response Surface Methodology (RSM) and a continuously operating system in a fixed bed column. The independent variables in the research are X1 (bed height), X2 (contact time), and X3 (flow rate). The dependent variable is Y1 (removal efficiency) with a matrix design by Box-Behnken. The optimum condition of methylene blue (MB) B removal was found at X1=16 cm, X2=90 min, and X3=4 L/min with an adsorption efficiency of 90.45%. After the activation and adsorption of MB dye, the complete FTIR spectrum shows a distinct peak at 2933.7 cm-1. The results of the EDX analysis performed on tea waste reveal the presence of nitrogen (element N) following the adsorption process. This observation strongly suggests that the tea waste has effectively absorbed MB, as nitrogen is a constituent element found in the molecular structure of MB.

Abstract

Methyl red is an azo compound widely applied in the textile industry as a fabric dye. Methyl red is very difficult to decompose because it is stable to light, temperature, and oxidation. One of the simplest and low-cost methods is adsorption. This study aims to determine the characteristics of bottom ash as an adsorbent and analyze the adsorption process with a fixed-bed column system. The research was conducted by varying the flow rate of 5, 10, and 15 L/min, adsorbent bed height of 4, 8, and 12 cm, and contact time of 60, 120, and 180 minutes. The highest removal efficiency, 93%, was achieved at a contact time of 180 minutes, a flow rate of 5 L/min, and a bed height of 12 cm. The physical properties of the bottom ash adsorbent include a pore volume of 0.0032 cm3/g, a specific surface area of 89.801 m2/g, and an average pore size of 58.523 nm. The maximum adsorption capacity was found to be 0.850 mg/g. The adsorption process of methyl red onto bottom ash follows the Langmuir isotherm model.
