“…The higher R 2 regression and lower difference between the q e,exp and q e,theor show that the experimental data were well-fitted to the pseudo-second-order model. The fit of this model indicates that adsorption rate is controlled by chemisorption process, which involves valence forces from the sharing of electrons between dye molecules and material surface (Foo et al, 2012;Silva 2016). Other studies related to adsorption of the same dye on different adsorbents demonstrated the same behavior (Pereira et al, 2017;Silva et al, 2012;Malakootian et al, 2015).…”

“…Sewage sludge is one of the adsorbent materials included in activated carbon solid waste categories. In addition, several sewage sludge based adsorbent has been used to remove pollutants [22,[66][67][68]. These adsorbent can be produced using different activation process to adsorb metals and dye from wastewater [22].…”

“…The most used adsorbent in removing colours and other pollutants include heavy metal from effluents is activated carbon. However, conventional activated carbon that been used today are expensive for a large scale of treatment [21][22][23]. Recently, the researchers has been focus on the development of low cost adsorbent for a full scale treatment [5,24,25].…”

Abstract. Industrial company such as textile, leather, cosmetics, paper and plastic generated wastewater containing large amount of dye colour. The removal of dye materials are importance as the presence of this kind of pollutant influence the quality of water and makes it aesthetically unpleasant. As their chemical structures are complicated, it is difficult to treat dyes with municipal waste treatment operations. Even a small quantity of dye does cause high visibility and undesirability. There have been various treatment technique reviewed for the removal of dye in wastewater. However, these treatment process has made it to another expensive treatment method. This review focus on the application of adsorbent in dye removal from textile wastewater as the most economical and effective method, adsorption has become the most preferred method to remove dye. The review provides literature information about different basis materials used to produce activated carbon like agricultural waste and industrial waste as well as the operational parameters factors in term of contact time, adsorbent dosage, pH solution and initial dye concentration that will affect the process in removing textile dye. This review approach the low cost and environmental friendly adsorbent for replacing conventional activated carbon.

“…This demonstrates the importance of efficient adsorbent materials for the removal of dyes from industrial effluents. NCMs, owing to their large surface area and well developed porosity, show excellent adsorption capacity for both neutral and charged pollutants including colorful dyes [6][7][8][9][10]. Adsorption phenomena depend both on the pore volume and surface area of NCMs.…”

Abstract:In this paper, wool carpet dye adsorption properties of nanoporous activated carbon materials (NCMs) prepared from bamboo agro-product is reported. Bamboo cane powder was chemically activated with phosphoric acid at different temperatures (400, 500, and 600 • C) at an impregnation ratio of 1:1. We found that the specific surface area and the total pore volume of NCM increases with temperature giving the highest surface area and pore volume ca. 2130 m 2 ·g −1 and 2.69 cc·g −1 at 600 • C. Owing to superior surface textural properties, bamboo-derived NCM showed excellent adsorption capacity for wool carpet dyes Lanasyn orange (LO) and Lanasyn gray (LG). The adsorption phenomena could be described by Langmuir/Freundlich adsorption isotherm models. The maximum adsorption capacity was ca. 2.60 × 10 3 and 3.04 × 10 3 mg·g −1 for LO and LG, respectively. The adsorption followed pseudo second order kinetics with the second order rate constant of 1.24 × 10 −3 g·mg −1 ·min −1 (LO) and 7.69 × 10 −4 g·mg −1 ·min −1 (LG), respectively. This study demonstrated that the high surface area NCMs prepared from agro-product can be used as efficient and cost-effective adsorbent materials for the removal of dyes from industrial effluent.
