Cellulose nanocrystal-reinforced keratin bioadsorbent for effective removal of dyes from aqueous solution

Removal of Cationic Dyes from Aqueous Solution using Organomodified Nanoclay

In this work, organomodified nanoclay has been used as the adsorbent for the removal ofbasic blue 41, cationic dye from an aqueous solution. The performance of the organomodified nanoclay was tested in a batch system under varying pH (2–12), adsorbent dosage (0.1–2 g L-1), initial dye concentration (10–60 mgL-1), and contact time (5- 100 min). The best conditions were achieved at pH of 7,...

Efficiency of Aptenia Cordifolia Mucilage in Removal of Anion Dyes from Aqueous Solution

Dye-containing wastewater is one of the main environmental challenges that can cause health issues. It is crucial to remove the dyes from wastewater before its discharge into the environment. This study aims to evaluate the efficiency of aptenia cordifolia mucilage in removal of anionic dyes from textile wastewater via coagulation and flocculation process. To this goal, the effect of different ...

Cellulose nanocrystal reinforced oxidized natural rubber nanocomposites.

Natural rubber (NR) latex particles were oxidized using KMnO4 as oxidant to promote the insertion of hydroxyl groups in the surface polyisoprene chains. Different degrees of oxidation were investigated. Both unoxidized and oxidized NR (ONR) latex were used to prepare nanocomposite films reinforced with cellulose nanocrystals (CNCs) by casting/evaporation. The oxidation of NR was carried out to ...

Potential of Cellulose Functionalized with Carboxylic Acid as Biosorbent for the Removal of Cationic Dyes in Aqueous Solution.

In the last decade, adsorption has been used to minimize the pollution caused by dyes, which represents a serious environmental problem. In this context, this work reports the preparation of phthalic anhydride-modified cellulose (PhCel), through the reaction of cellulose (Cel) with phthalic anhydride (Ph). The efficiency of the reaction was observed by elemental analysis, Fourier Transform Infr...
