“…From Table , the adsorption capacity of the TPP-SH adsorbent for MB and MG both higher than that of reported adsorbent polymers. − The excellent adsorption property of the novel polymer TPP-SH could be attributed to its large specific surface area, rich porosity, and even functional groups (−SH). Therefore, the polymer TPP-SH may be the most promising adsorbent as an efficient alterative for dye removal.…”

It is of great significance to develop new materials for efficient capture cationic dyes methylene blue (MB) and malachite green (MG). In this work, a novel triptycene-based porous organic polymer with abundant thiol groups (TPP-SH) was prepared successfully by postmodification with a high surface area and robust triptycene-based porous organic polymer (TPP). The obtained TPP-SH exhibited a high surface area, good porosity, and good thermal stability. In addition, TPP-SH was highly effective at capturing MB and MG from aqueous solution because of the abundant thiols in its hierarchical structure. Under optimal adsorption conditions, the maximum adsorption capacities of MB and MG calculated by the Langmuir model at room temperature were 1146.3 and 689.6 mg g –1 , respectively. These values are higher than those of many reported materials. The MB and MG adsorption rates were 0.0154 and 6.69 × 10 –4 mg g –1 min –1 , respectively. Furthermore, the polymer TPP-SH had a good recycling performance after adsorption–desorption at least five times. Therefore, the TPP-SH exhibited a high adsorption capacity, fast adsorption kinetics, and easy-recycling behavior, providing a new avenue for the preparation of green functionalized adsorbents with good performance for water decontamination.

“…Besides being simple in design, another supremacy of AC is its versatility in treating wide ranges of pollutants, namely, dyes 4–6, heavy metals 7, pesticides 8, antibiotic 9, and many more. For the past two decades, researchers are more interested to use agrowaste as AC precursor such as acacia sawdust 4 pomegranate peel 10, peanut shell 11, and Alpinia galanga stem 12. This is because agrowaste can be obtained in a large quantity and they can be activated using a microwave oven.…”

The toxicity of heavy metals motivated the synthesis of coconut shell‐based activated carbon (CSAC) through single‐stage microwave irradiation technique to scavenge cadmium ions (Cd(II)). Response surface methodology revealed the optimum radiation power and radiation time which translated into 85.45 % of Cd(II) removal and 41.78 % of CSAC's yield. Isotherm and kinetic data were best described by Freundlich and pseudo‐first‐order (PFO) models, respectively. The changes of enthalpy, entropy, and activation energy were determined as well as the reduction of CSAC yield and Cd(II) removal after six regeneration cycles.

“…However, two decades ago, AC was struggling with the issue of high production costs due to the usage of the nonrenewable precursors coal, lignite, and petroleum coke . Alternatively, researchers have been actively producing AC from agricultural wastes such as Gelidiella acerosa seaweed, durian peel, peanut shell, coconut shell, biomass sludge, and alpinia galanga stem . Date palm ( Pheonix dactylifera L .)…”

Remazol Brilliant Blue R (RBBR) is a common dye used in the industry, and its presence in wastewater and discharge into the environment can create a serious concern for the ecosystem and human health. Activated carbon produced from crop residues has emerged as a promising technique for removing contaminants from wastewater. In this study, leaf sheath date palm fiber-based activated carbon (LSDAC) was synthesized via phosphoric acid, H 3 PO 4 , treatment, followed by a microwaveinduced carbonization process. The produced LSDAC was found to have a BET surface area of 604.61 m 2 /g, a Langmuir surface area of 922.05 m 2 /g, a total pore volume of 0.35 cm 3 /g, and an average pore size of 2.75 nm. The highest removal of RBBR was achieved at a solution pH of 3 (92.56 mg/g) and a solution temperature of 50 °C (90.37 mg/g). Adsorption of RBBR onto LSDAC followed the Langmuir isotherm model with a maximum monolayer capacity, Q m , of 243.43 mg/g, whereas in terms of kinetics, this adsorption system was best described by the pseudo-first-order (PFO) model. The calculated thermodynamic parameters ΔH°, ΔS°, ΔG°, and Arrhenius activation energy, E a , were 4.71 kJ/mol, 0.10 kJ/mol•K, −26.25 kJ/mol, and 5.88 kJ/mol, respectively, indicating that the adsorption of RBBR onto LSDAC was endothermic in nature, exhibited increased randomness at the solid−liquid interface, and was spontaneous and controlled by physisorption.
