“…These easily available agricultural waste may have a variable characteristic of each materials and each of the materials or adsorbent has its own feature in the treatment for wastewater that will influence the adsorbent properties parameter. As example sugarcane bagasse effective in removing acid dye [35], grape marc-based in removing reactive dye [47] and coconut shell offer effective removal of basic dye but a bit lower for direct dye [11].Yet, the variables and condition in adsorption process also influence the effectiveness of treatment including dose of adsorbent, contact time, adsorbent concentration, pH value and temperature. To ensure the adsorbent effectively can be used for industrial scale, further investigation on development of adsorption process for real condition of wastewater need to be conducted as the industrial effluents containing several pollutants simultaneously.…”

“…Various studied by researchers has been conduct on raw and activated carbon agricultural waste [50] such as sugarcane bagasse [8,18,[50][51][52][53][54][55], olive stone [56], date pits [20],langsat peel [34], apple waste [42], macadamia shell [57], rice husk [52], orange peel [58], prosopis juliflora plant [59], bamboo [60], corncob [41], coffee residue [61], pomegranate peel [1,32], coconut shell [11,62] etc. These agricultural waste have been investigated for various dye removal from aqueous solution such as basic dye [15,[63][64], direct dye [11], benzidine-based dye [6], reactive dye [47,65] and others. Wan suraya et al [44] have been studied the potential of sugarcane bagasse to be an alternative for conventional activated carbon.…”

“…The coloured wastewater are unpleasant and heavily pollute the environment. Dyes present in industrial wastewater are carcinogenic, mutagenic, teratogenic and toxic [11]. In addition, most of dye leads to hazardous affects not only to animal and human health but also microorganisms [12][13][14].…”

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.

“…Low cost coconut shell based activated carbon (CSAC) was also examined for removal of Reactive Blue 19 (RB19) dye adsorption from aqueous solution [6]. Activated carbon from coconut shell was prepared via H 2 SO 4 activation (CSAC) and its ability to remove textile dyes; maxilon blue GRL and direct yellow DY 12, from aqueous solutions were studied [7]. In this study, we attempt to investigate the removal ability of basic dyes from solution by coconut shell charcoal, which is agricultural waste in the community.…”

Abstract. This research aims to use agricultural waste as an adsorbent for dye removal from textile wastewater. Coconut shell charcoal (CSC), an agricultural waste, was used as dye adsorbent whilst basic yellow13 (BY13) and basic red14 (BR14) were used as representative dye used in textile manufactory. The removal of BY13 and BR14 from aqueous solution by CSC was investigated in batch adsorption at room temperature. Two parameters investigated in this research were pH of dyes solution; pH 2, 7, and 11, and particle size of adsorbents; 510-700 μm and 1000-2000 μm. The adsorption model, Langmuir and Freundlich were also examined. It was found that by CSC, BY13 and BR14 had maximum removal percentage of 23.6 and 55.7 at pH 11. Size of adsorbent had also shown the effect on dye removal, i.e.; increasing size with decreasing removal capability. The dye removal experimental data were fitted to Langmuir adsorption model for both dyes with maximum adsorption capacity (qm) for BY13 and BR14 of 19.76 and 22.93 mg/g, respectively. It can be implied that the adsorption is monolayer. It can conclude that CSC can be used as adsorbent for basic dye removal from aqueous solution.

“…Water pollution (surface and groundwater) is one of the most undesirable environmental problems and requires rapid and efficient solutions. Among the inorganic and organic pollutants present in wastewater, dyes represent a strong threat because these contaminants are highly toxic, carcinogenic, mutagenic and teratogenic for human beings, fish species and microorganisms [1][2][3]. From literature, a series of physical, chemical and biological measures for the removal of dyes from effluents have been developed, such as adsorption [4][5][6], membrane separation [7], chemical coagulation [8,9], electrochemical method [10], or oxidative processes [11,12].…”

ABSTRACT. This paper presents a report on kinetics of malachite green (MG) dye removal from model aqueous solutions using a biomaterial formed by corn cob activated carbon (CCAC). The sorbent was characterized using specific surface area and pore size distribution (Brunauer-Emmett-Teller, BET) analysis. The BET analysis confirmed the macro-porosity of the adsorbent. Effects of initial concentration of MG dye and CCAC quantity, particle size and stirring rate on adsorption capacities and efficiency were monitored through pseudo first-and second-order models, intra-particle and film diffusion models to present adsorption rate parameters. The removal efficiency of MG increased with the adsorbent quantity and particle size.
