The resources of clean water worldwide are very limited, and climate change is already affecting the available supplies. Therefore, developing a low-cost, highly efficient, and recyclable adsorbent to upgrade water quality has become an essential task. Herein, we report the fabrication of activated carbon (AC) adsorbents derived from lignocellulosic wastes. Both phys. and chem. activation were investigated to modify the surface texture properties. The results indicated that increasing the activation temperature, whether phys. or chem., increases the sp. surface area (SBET). On the contrary, increasing the amount of the chem. activating agent significantly decreases the SBET values. The SBET of 1771, 2120, and 2490 m2 g-1 were obtained for water vapor, K2CO3 and KOH, at activation temperatures of 950掳C, 800掳C, and 800掳C, resp. Methylene blue (MB) and phenol were used as adsorbates for the adsorption experiment Adsorption of methylene blue dye revealed the ability of the water activated carbon to remove more than 95% of the dye (100 ppm) within 5 min with an adsorption capacity of 148.8 mg g-1. For phenol adsorption, Several parameters were investigated, including initial concentration (50-250 ppm), pH (2-10), contact time (5-60 min), and temperature (25-45掳C). The highest adsorption capacity of phenol achieved was 158.9 mg g-1. The kinetics of adsorption of phenol was better described by pseudo-second-order reaction while the isotherm process using Langmuir model. This study presents a roadmap for conversion of lignocellulosic biomass waste into highly efficient porous carbon adsorbents. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Application In Synthesis of 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride).
3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Application In Synthesis of 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride
