Abstract

The Industrial release of synthetic dyes, such as methylene blue (MB), into water has created significant environmental concerns. The use of date trunk as a bio-adsorbent was investigated for the removal of MB dye from wastewater. The effects of several experimental parameters, such as MB dye concentration, contact time, and adsorbent dosage, were studied using a batch-laboratory operational setup. Fourier Transform Infrared (FTIR) spectroscopy was performed to reveal the presence of functional groups in the bio-adsorbent. This study evaluated the adsorption capacity of a green bio-adsorbent for the removal of MB dye from wastewater. The maximum adsorption of MB was obtained for the bio-adsorbent dosage of 0.4 gram for 50 min. The Gaussian 09 software package was used for Density Functional Theory (DFT) to optimize the molecular structures of guaiacol and methylene blue (MB) dye. The results revealed that date trunks have great potential as efficient bio-adsorbents for the removal of MB dye from wastewater.
