Removal of anionic dyes (Reactive Black 5 and Congo Red) from aqueous solutions using Banana Peel Powder as an adsorbent

Study of the Ziziphus Joazeiro Peel for Indigo Blue Adsorption.

“…Raymundo et al (2010) utilized sugar-cane bagasse as bioadsorbent in the textile wastewater treatment contaminated with congo red dye. Munagapat et al (2018) investigated the removal of anionic dyes (Reactive Black 5 and Congo Red) from aqueous solutions using banana peel powder as an natural adsorbent. Zhu et al (2016) utilized cellulose and chitosan for removal of toxic IB.…”

In vitro and in vivo assessment of banana peel powder as an aflatoxins biosorbent

“…The lowest value of aflatoxins adsorption (24.2%) was obtained at 0.5% banana peel with the highest aflatoxins concentration after 1h contact time (Table 2). High ability of banana peel powder as an adsorbent to remove of anionic dyes from aqueous solution was reported by Munagapati et al (2018). They also concluded that the adsorption increases by increasing contact time because banana peel has an irregular and porous surface which is adequate for adsorption.…”

Adsorption of acid red 114 and reactive black 5 in aqueous solutions on dendrimer‐conjugated magnetic nanoparticles

“…[59] The calculated isotherm parameters of two anionic dyes from both models are shown in Table 2. [60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77][78][79] Though Fe 3 O 4 @SiO 2 -TRIS has a large number of terminal hydroxyl groups, their maximum dye binding capacity is less than that of Fe 3 O 4 @SiO 2 -MPAP [41] and Fe 3 O 4 @SiO 2 -NH 2. It indicates that the adsorption occurs at specific homogeneous sites within the adsorbent, forming a monolayer coating of the dye at the surface of the adsorbent.…”
