Performance of Waste Activated Carbon as a Low-Cost Adsorbent for the Removal of Anionic Surfactant from Aquatic Environment

Abstract

In the present study, different low cost adsorbents were screened for their sodium dodecyl sulfate (SDS, an anionic surfactant) removal capacity. Waste activated carbon (WAC) from the aqua purifier has shown high efficiency for SDS removal. The performance evaluation in the presence of various ions (Ca2+, SO4(2-), NO3-, and Cl-) and at various pH was studied. Desorption studies were conducted using simple sonication and pH variation technique. Column adsorption studies were performed. SEM and EDS studies were done on the adsorbing material before adsorption, after adsorption and after desorption of SDS.

Synthesis of Water‐Soluble Large Naturalised Dyes Through Double Glycoconjugation

“…The synergistic effect with other toxic chemicals that may be present in waste waters increases their negative effects on the environment. [3] In this context, the surfactants present in the waste waters of textile industries must be reduced to acceptable levels before being discharged into the environ- when a single molecule of lactose was added through a bivalent spacer, which is in contrast to the smaller dyes. To overcome this difficulty, herein we present the first approach to the insertion of two lactose units by a double glycoconjugation process.…”

Adsorption of cationic and anionic surfactants onto organic polymer resin Lewatit VPOC 1064 MD PH

“…The synthetic surfactants are classified into four major types according to their head group: anionic, cationic, nonionic, and amphoteric (Scott and Jones 2000;Gupta et al 2003;Cserháti et al 2002). The applications of surfactants in science and industry are legion, ranging from primary processes such as the recovery and purification of raw materials in the mining and petroleum industries, to enhancing the quality of finished products such as paints, cosmetics, pharmaceuticals, and foods (Myers 1999;Meesters and Schröder 2004).…”

Reliable Technique for the Determination of Sodium Dodecyl Sulphate by Crystal Violet in Relation to the Effluents of Durg‐Bhilai Region

“…The use of surfactant is gradually increasing day by day. It has been reported [1][2][3] that the world surfactant production was 1.7, 1.8 & 4.3 MT in the year 1984, 1987 & 1995 respectively. In domestic waste water produced by the house holds, surfactants invariably exist in significant amount due to the enormous use of detergents for washing purpose.…”

“…Reported in effluent, concentration of LAS in domestic waste water range from 3-21 mg/ltr. 3 Surfactants are harmful 4 to human being, fishes and vegetation. They are responsible for causing foams in rivers and effluent treatment plants and reduced the quality of water.…”
