“…The potential of coconut leaf mesoporous-activated carbon prepared via microwave-induced H 3 PO 4 activation using batch process for MB dye removal was investigated [114]. Experiments were carried as a function of contact time (0-360 min), adsorbent dose (0.2-10 g/L), initial concentration (50-350 mg/L) and initial pH (3−10).…”

The presence of organic dyes in the aquatic environment is a serious global problem because of the serious negative consequences on the quality of ecosystems. Among various physico-chemical methods, the adsorption could be considered a promising alternative for removing dyes from aqueous media, due to its efficiency, high selectivity, low cost, ease of operation, simplicity, and availability in a wide range of experimental conditions. However, all these advantages are closely related to the nature of adsorbent material used in the adsorption processes of dyes. The adsorbent materials available in large quantities requiring a simple preparation will enhance the benefits of the adsorption processes, in agreement with the concepts of green chemistry. This review is focused on the use of leaf-based materials, in raw or modified forms, as adsorbents for the removal of dyes from aqueous effluents, with applications in the wastewater treatment. This review addresses characterization of leaf-based adsorbents, possible utilization of leaf-based adsorbents (raw and activated forms) for dye removal and possible applications in pilot and full scale systems. Also, thermodynamics, equilibrium and kinetic parameters of dye adsorption on leaf-based adsorbents are discussed. The practical utility of leaf-based adsorbents for dye removal, and their possible uses in the treatment of industrial wastewater are copiously highlighted.

“…The experiments were carried out in a series of Erlenmeyer flask (250 mL) containing MB dye solution (100 mL) with different initial MB dye concentrations (25-200 mg/L). The different dosages of SATCS (0.02-0.2 g) were added to the 100 mL of MB dye solution with different levels of pH (3)(4)(5)(6)(7)(8)(9)(10), and agitated at a fixed shaking speed of 110 strokes/min at 303 K by using a water bath (WNB7-45, Memmert, Germany). After the adsorption process, the adsorbents was separated from aqueous solutions using a syringe filter (0.20 µm), and the MB dye uptake was calculated by UV-Vis spectroscopy (HACH DR 2800) at 661 nm.…”

“…Methylene blue (MB) dye is widely used in the textile industry for dyeing cotton, wood, and leather, in addition to the pharmaceutical industries [3]. MB dye causes harmful effects on human health such as nausea, vomiting, heart rate increasing and eye/skin irritation [4,5]. Several methods were applied to remove textile dyes prior to discharge into water such as adsorption [6], photocatalysis [7], oxidation [8], and coagulation [9].…”

Coconut (Cocos nucifera) shell was chemically treated with sulfuric acid (H2SO4) to produce acid-factionalized biosorbent for methylene blue (MB) dye removal from aqueous environment. Various analytical techniques were utilized to investigate the surface area, surface morphology, crystallinity, elemental composition, and functional group of the sulfuric acid-treated coconut shell (SATCS). The adsorption parameters such as adsorbent dosage (0.02-0.20 g), solution pH (3-10), contact time (0-360 min), and initial MB dye concentration (25-200 mg/L) were studied. The adsorption results were illustrated by pseudo-second order kinetic and Freundlich isotherm models. It was found that SATCS has a maximum adsorption capacity (q max) of 50.6 mg/g at 303 K. The adsorption mechanism of MB dye on the SATCS surface can be assigned to the various types of interactions such as electrostatic attractions, H-bonding interaction, and π-π interaction. This work shows SATCS as promising acid-factionalized biosorbent for removal MB dye.

“…Owing to its high water solubility, wastewater containing MB is hazardous to environment and human health. It causes a noticeable coloration and classified as toxic colorants at concentration as low as 1 mg/L [5]. Due to this fact, the discharged of MB into water bodies contribute major aesthetic and ecological problems.…”

Acid-treated banana peel (ATBP) was developed by H 2 SO 4 activation to be a potential adsorbent for methylene blue (MB) from aqueous solution. Batch mode adsorption studies were conducted by varying adsorbent dosage (0.02-0.30 g), solution pH (3-12), initial MB concentrations (10-300 mg/L) and contact time (0-1440 min). The adsorption data of MB by ATBP were in agreement with Langmuir isotherm, with maximum adsorption capacities of 250 mg/g at 303 K. The pseudo-first-order kinetic model best described the kinetic data. The adsorption of MB onto ATBP surface was endothermic in nature and spontaneous under the experimented conditions. Results supported the potential use of the ATBP as an effective adsorbent for the treatment of cationic dyes such as MB from aqueous solution. ARTICLE HISTORY
