“…It can be concluded that adsorption of safranin dye onto NHBT best fitted on pseudo-second order rate model, which indicates that the adsorption process is a rate limiting step which involves forces to share or exchange electrons between adsorbate and adsorbent. Similar results were reported by Kumar andKumar, 2015 andFayazi. et al 2015 [10, 13].…”

“…adequate dose of 1 gm/l was added into the solution and agitated at 200 rpm for 90 minutes in rotary shaker. The effect of pH (3,5,6,7,8,10), adsorbent dose (1-10 ) gm/l, contact time (5, 10, 15, 20, 30, 45, 60, 90 minutes) were studied. At regular interval, samples were collected and examined in UV-VIS Spectrophotometer.…”

The review study focuses on dye contamination of wastewater and adsorption approaches to achieve the lowest dye waste in wastewater discharge. The dyes require extensive use in several applications suited for commercial consumption, but the dyes are serious pollutants when dumped directly into water bodies without sufficient treatment. The review study briefly discusses the current methodologies carried out for the adsorption mechanism, the relevance of adsorption, and adsorption factors for the examined system. Langmuir and Freundlich isotherm models and a pseudosecond order kinetic model were found to properly represent dye uptake. To fully appreciate the molecular interactions between the adsorbent and adsorbate, additional study into theoretical dye adsorption modeling is necessary. As a low-cost adsorbent for dye treatment and the manufacturing of activated carbon, agricultural waste material in both its natural and modified forms is explored in this review article for its dye adsorption capabilities. The adsorption behavior and mechanism may be better understood by employing operational parameters, kinetics, and isotherm models, as described in this article. The initial concentration, pH, and temperature all play a function in the adsorption process and are discussed in depth.

“…Among all, the industries which are using dyes in their manufacturing process or manufacturing dyes itself contribute a lot in terms of water pollution (Yaseen & Scholz, 2019). It is obvious that the effluent coming out from these industries cannot be discharged into water bodies without treatment as it will be harmful for both aquatic and human life (Chequer et al, 2013;Kumar & Kumar, 2015;Lellis et al, 2019).…”

In the present article, an attempt is made for simple, low-cost, and efficient removal of Auramine dye using peanut (Arachis hypogaea) shells as adsorbents. Two different forms of adsorbents distilled water washed peanut shells (DPS) and NaOH treated peanut shells (NPS) were used as adsorbents. Both the adsorbents were studied using BET, pH PZC , FTIR, SEM, TGA, and XRD characterization techniques. Adsorption parameters such as effect of contact time, pH, initial dye concentration, adsorbent dose, and temperature were also assessed. Isotherm analysis at optimum conditions showed Langmuir fitted better with a q m value of 96.15 mg/g for DPS and 294.12 mg/g for NPS; while in kinetic analysis, pseudo-second order was superior. Thermodynamics study stated that adsorption process was endothermic in nature. Overall outcomes establish that the two forms of peanut shells, DPS, and NPS were excellent in removal of Auramine dye and are low cost also as preparation cost of DPS and NPS is 68.73 INR and 106.19 INR per kg, respectively. © 2020 Water Environment Federation • Practitioner points • Removal of Auramine dye from aqueous media using different forms of peanut (Arachis hypogaea) shells as adsorbents is discussed. • q m (Langmuir) using DPS and NPS were found to be 96.15 and 294.12 mg/g, respectively. • Preparation cost of DPS was 68.73 INR per 1 kg, whereas for NPS it was 106.19 INR per 1 kg.
