BATCH ADSORPTION AND ISOTHERM STUDIES FOR THE REMOVAL OF MALACHITE GREEN AND REACTIVE RED 4 DYES BY USING AC-MnO2-NC PREPARED FROM Typha angustat L.

Abstract

The potential of using Typha Angustata L modified AC-MnO2-NC to eliminate the dyes namely Malachite Green and Reactive Red 4 dyes are studied. The result of more than a few parameters such as adsorbent dosage, contact time, temperature, the initial concentration of the adsorbate and pH has been evaluated. Tempkin, Halsey, Langmuir, Dubinin-Radushkevich and Freundlich isotherms are too studied. The lessons exposed that AC-MnO2-NC is appropriate to employ as an adsorbent to take away both Malachite Green and Reactive Red 4 dyes.

A review of biomaterial as an adsorbent: From the bibliometric literature review, the definition of dyes and adsorbent, the adsorption phenomena and isotherm models, factors affecting the adsorption process, to the use of typha species waste as adsorbent

“…It also presents the potential of the adsorption process by means of Typha biomaterial wastes for the removal of dyes from textile wastewater. Furthermore, this paper provides a brief discussion about a number of Typha angustoflia Methylene blue 106.373 [126] Typha angustoflia Malachite green 72.25 [129] Typha latifolia Methylene blue 126.6 [130] Typha australis Malachite green 85.21 [131] Typha australis Congo red 17.40 [132] Typha latifolia Methylene blue 21.07 [133] Typha latifolia Methylene blue 54.73 [133] Typha latifolia Methyl orange 36 [134] Typha angustota Reactive red 4 100 [135] Sugarcane dust Malachite green 3.999 [138] Sugarcane dust Basic violet 10 3.240 [138] Banana pith Acid brilliant blue 4.42 [139] Neem sawdust Methylene blue 3.42 [140] Coit pith Acid violet 1.65 [141] Orange peel Basic violet 10 14.3 [91] Beach sawdust Basic blue 9 9.78 [142] Water hyacinth root powder Methylene blue 8.04 [143] cashew nut shell Congo red 5.184 [144] de-oiled biomass Acid fuchsin 9.9 [145] determining factors (i.e. contact time, pH condition, adsorbent amount, and initial dye concentration) towards dye adsorption.…”

“…Among the researchers, regarding the adsorption modeling, Freundlich, Langmuir, and Redlich-Peterson isotherm models are the most commonly employed isotherms for different Typha biomaterial wastes adsorbents/dye systems. [125,126,[129][130][131][132][133][134][135]. The following results are briefly presented by researchers:…”

“…Table 6 depicts the adsorption capacity and other parameters for the dye removal by the different Typha biomaterials and other agricultural wastes as the affordable adsorbents. The studies of dyes adsorption by Typha species wastes as adsorbents presented a higher adsorption capacity for cationic dyes than an adsorption capacity for anionic dyes proving the viability of Typha biomaterial wastes as one of the most effective adsorbents for the dyes removal from aqueous solutions in comparison to other agricultural waste adsorbents as studied in the literature [91,125,126,[129][130][131][132][133][134][135][138][139][140][141][142][143][144][145]. Therefore, the removal of cationic and anionic dye contaminants from wastewaters using Typha biomaterial wastes, in a natural form, offers the prospective outcomes with maximum adsorption efficiency in the field of adsorption technology for showing the outstanding removal capabilities for various classes of dyes and could be exploited as an alternative to the use of commercial activated carbon.…”

Utilization of Unwanted Terrestrial Weeds for Removal of Dyes

“…Low-cost adsorbents require little processing and found abundantly in nature. The various low cost adsorbents have been investigated by researchers like agricultural waste, 4 banana peel, 5 Ficus carica, 6 apple peels, 7 apricot stone, 8 bagasse fly ash, 9 peat, 10 abundant weeds, 11 walnut shell, 12 soya waste, 13 hen feather, 14 oil palm midrib, 15 sugarcane baggase, 16 Typha angustifolia, 17 natural zeolites, 18 sewage sludge, 19 etc. The objective of the present work is to study the adsorption of congo red (CR), methylene blue (MB) and crystal violet (CV) on dead biomass of weeds Parthenium hysterophorus and Saccharum munja.…”

REMOVAL OF ACID GREEN 25 DYE BY USING ACTIVATED CARBON PREPARED FROM PassifloraFoetida[PAC-MnO2- NC]NANOCOMPOSITEIN BATCH ADSORPTION-KINETIC STUDY

“…Many of the organic dyes are dangerous and may distress food chain and even aquatic life. Discharge of these dyes in a watercourse is aesthetically undesirable 2 . The release of tint in the surroundings is disturbing for both esthetical and toxicological reason as dyes delay light diffusion, spoil the value of the getting stream and are poisonous to foodstuff organisms 3 .The rapid development of the textile industry in developing countries has triggered an increase in pollution of the aquatic environment 4 .…”
