The Removal of Dye from Aqueous Solution by Adsorption on Low Cost Adsorbents

Abstract

Removal of color from aqueous solution by using low cost easily available adsorbent was conducted by batch experiment. The potential of the low cost adsorbent (Marble powder-treated and untreated) to remove methylene red from aqueous solution were assessed at room temperature. Laboratory investigation of the potential of marble powder and sulphuric acid treated marble powder to remove dye color from aqueous solution has been studied. Parameters studied included pH, adsorbent dose, initial dye concentration and contact time. The influence of these system variables were investigated to observe the effect on the rate of dye uptake. Sulphuric acid treated marble powder has shown better adsorptive capacity than untreated marble powder and thus it has become an interesting option for dye removal from industrial effluents.

Removal of Bromocresol Green from Aqueous Solution via Adsorption on Ziziphus nummularia as a New, Natural, and Low-Cost Adsorbent: Kinetic and Thermodynamic Study of Removal Process

“…The adsorbent materials were collected and washed with distilled water to remove dirt and impurities and dried in the sun, and then for acid treatment it was mixed with concentrated hydrochloric acid (37 %) at room temperature for 24 h. The sample was then washed several times with distilled water, filtrated, dried at 120 °C for 1 h, and sieved to the particle sizes through 10-50 mesh. The product obtained was stored in a closed container for further tests …”

Adsorption of bromophenol blue and bromothymol blue dyes onto raw maize cob

“…In this work the amount of raw maize cob was varied from 0.5 to 4.0 g (fig 4) in order to test the effect of adsorbent dosage on the adsorption of these dyes with other parameters kept constant. BPB dye adsorption increases with increase in the dosage from 0.5 g to 4.0 g from 21.11 % to 64.68 %, which may be attributed to the fact the number of available adsorption sites increases by increasing the adsorbent dose (Charles and Odoemelam 2010;Chamargore et al, 2010;Balasubramani and Sivarajaseka 2014;Patil et al, 2011;Jimoh and Ibrahim 2017;Dim, 2013). While for BTB increase in the dosage from 0.5 g to 4.0 g leads to decrease in the removal efficiency of the dye from 53.69 % to 13.79 %.…”

Adsorption Kinects and Isotherms for Removal of Rhodamine B (dye) using Adsorbents prepared from drinking water treatment sludge

“…The cost is actually an important parameter for comparison and selection of adsorbents. The literature survey reveals that there has been numerous researchs reported the using of low cost adsorbents for dye removal, which are economical viable, easily available, highly effective in the adsorption process (Chamargore et al, 2010). Low-cost adsorbents have been studied for the removal of dyes and heavy metals from wastewater such as waste apricot (Sun and Yang , 2003), coconut shell (Kumar and Porkodi ,2007), dairy sludge (Gong et al, 2005) , bamboo grass treated with concentrated sulfuric acid (Sumanjit and Prasad ,2001), peat (Sumanjit et al,2010), bamboo (Ma et al,2010), jack fruit peels (Jai and Jayaram ,2007), pistachio nut shells (Vijayalakshmi et al,2011), date stone and palm tree waste (Belala et al, 2011), treated sewage sludge (Rashed et al, 2011), and phosphate slime (Rashed et al,2015).…”
