Abstract
Here we report about the utilization of patchouli dregs which are disposed waste from the production of patchouli oil production as a material source of biosorbent. This biosorbent offers a lot of merits such as being environmentally friendly, and low manufacturing costs. The biosorbent was derived from patchouli dregs which was physically activated at a temperature of 350 °C. Scanning electron microscopy (SEM) was used to study the morphological structure of the material that was obtained. X-ray diffraction (XRD) was used to determine the crystalline structure of the material, and Fourier transform infrared (FTIR) spectroscopy was used to determine the functional group of the compound. According to the findings, the activated patchouli dregs sorbent had an optimum adsorption capacity for methylene blue of 1.871 mg/g and an adsorption efficiency of 96.11% with a contact time of 60 min, mass adsorbent of 0.4 g, and adsorbate concentration of 5 ppm.
