Development of a magnetic orange seed/Fe3O4 composite for the removal of methylene blue and crystal violet from aqueous media

Chitosan‐nTiO2 Nanocomposite Synthesis and its Adsorptive Removal Capacity for Methylene Blue from its Aqueous Solution: Batch Adsorption Study and Modeling

“…An exact quantity (1-7 gL À 1 ) of the adsorbent was placed in a capped conical flask holding MB solution (100 ml) of a definite concentration (10-100 mgL À 1 ) at experimental pH (3)(4)(5)(6)(7)(8)(9)(10)(11) for a specific experiment. NaOH (0.1 M) or HCl (0.1 M) solutions were employed dropwise for the pH adjustment of the experimental solution.…”

“…The solution's pH (3)(4)(5)(6)(7)(8)(9)(10)(11) effects on adsorption were studied for different adsorbents (Figure 4) with constant initial MB concentration, 10 mgL À 1 , with a constant adsorbent dose of 1 gL À 1 at room temperature. The MB percentage removal of MB improved with an increase in pH.…”

“…textile, paper, printing, dyeing, food process, rubber, and cosmetics, can arrest the penetration of light into the water, disturb the development of aquatic plants, and raise the suspended solids, BOD, COD, TOC and TSS content of water bodies. [6][7][8] MB is among the most utilized ingredients in the dye industry and is often used as a colourant for silk, wool, cotton, and paper. The Scopus record indicates that the number of MB removal publications has continuously increased since 2010-2020.…”

ZnO@ activated carbon derived from wood sawdust as adsorbent for removal of methyl red and methyl orange from aqueous solutions

“…The presence of dyes in water prevents sunlight from penetrating, which is a serious problem that leads to the eutrophication of water bodies and the demise of plants and animals. Thus, developing effective methods to remove artificial colors from water is highly desired 3 . Various techniques, including sono-photocatalytic degradation 4 , 5 , biological treatment 6 , and so on can be used for the elimination of dyes from wastewater.…”

Green synthesis of gold nanoparticles using macroalgae Halimeda macroloba extract and their photocatalytic degradation of methylene blue and methyl orange

“…The water supply is the source of life, and the presence of these poisons has a negative impact on the environment, putting the health of both humans and animals in jeopardy. Numerous produced goods, including textiles, pharmaceuticals, food, cosmetics, and agro‐allied sectors, make extensive use of organic dyes via their widespread use 5,6 . The reduced form of methylene orange (MO), which is an anionic azo dye that is frequently used in the textile, pharmaceutical, paper, leathers, printing, cosmetics, and food sectors, has the potential to be mutagenic.…”
