Abstract

Adsorption of synthetic dyes using low-rank coal as an adsorbent needs to be applied considering that adsorption is the best technology available and low cost to remove some toxic contaminants, both organic and inorganic contained in wastewater. In addition, the great potential of low rank coal in East Kalimantan is still abundant and not fully utilized because so far, several studies have focused on medium and high rank coal. This study aims to determine the dye removal of methylene blue (MB) on adsorption process using low rank coal as an adsorbent. 100 mg low rank coal adsorbent was added to 100 mL of 100 mg/L methylene blue dye solution at 30 °C. Initial pH effect adjusted with 0.10 mol/L of HCl or NaOH. Then the synthetic dye solution of methylene blue was shaker at 150 rpm based on different contact times (10 - 90 min). At the end of the period, the shaker was stopped, and the supernatants were filtered through a Whatman 40 filter paper to separate the liquid from the solid phase. The remaining synthetic dye concentrations of methylene blue were determined using UV-Vis Spectrophotometer at maximum wavelength (λmax) of adsorption. The experiment was repeated for different initial concentrations of synthetic dye methylene blue (50 – 250 mg/L). The best results were obtained using 100 mg low-rank coal adsorbent of East Kalimantan at optimum pH, initial concentration, and contact time, respectively as follows 12, 150 mg/L, and 10 minutes with methylene blue dye removal of 98.41%.
