Enhanced adsorptive removal of crystal violet dye from aqueous media using citric acid modified red-seaweed: experimental study combined with RSM process optimization

Polyaniline coated tungsten trioxide as an effective adsorbent for the removal of orange G dye from aqueous media

“…15 Adsorption is an alternative wastewater treatment process because of its high performance and ease of operation, as well as the possibility of regeneration. [16][17][18] Several adsorbents such as zeolite, cellulose, activated carbon, clay, and so on have been applied to remove dyes from wastewater. 16,18 The reported adsorbents present many drawbacks such as high cost of preparation, regeneration difficulty, and a long time to achieve adsorption equilibrium, thus restricting their large-scale application to treat textile effluents.…”

Recent Advancement in Rational Design Modulation of MXene: A Voyage from Environmental Remediation to Energy Conversion and Storage

“…Their presence even at low concentrations could cause severe environmental problems. [457][458][459] No doubt, the commonly used conventional strategies such as filtration, electro-dialysis and chemical precipitation are effective but the high cost restrict their application at large scale. [460,461] The removal of metal ions is very difficult owing to their low concentration (ppm to ppb) as compared to toxic dyes removal as their concentration is relatively higher in wastewater.…”

Isothermal and Kinetic Investigation of Exploring the Potential of Citric Acid-Treated Trapa natans and Citrullus lanatus Peels for Biosorptive Removal of Brilliant Green Dye from Water

“…It is a basic dye, and on dissolution in an aqueous solution, it provides cations (BGD + ). ese adsorbents were also treated with different chemicals separately, such as ethanol, methanol, isopropanol, 0.1 M HCl, and 0.1 M NaOH, and some chelating agents such as urea [30], thiourea [31], EDTA [32], tartaric acid [33,34], citric acid [35][36][37], lactic acid [38], and acetone [39]. Both adsorbents were chemically processed with organic solvents (ethanol, methanol, and isopropanol) for their modifications in glass beakers covered with aluminum sheets for a period of 3 to 4 hours.…”
