Removal of textile dye Reactive Black 5 from aqueous solution by adsorption on laccase-modified silica fume

The Investigation of Removing Direct Blue 15 Dye from Wastewater Using Magnetic Luffa sponge NPs

“…A distinctive feature of ZnO and Fe 3 O 4 NPs in the adsorption of this azo dye was not observed in the XRD spectrum. The values were very close to each other (Figure 8) [47][48][49].…”

“…The highest b value was achieved with the pure LS membrane form with 1.186 L/mg and the LS-ZnO/Fe 3 O 4 NPs membrane form with a minimum b value of 0.06 L/mg. High and randomness at the solid solution interface of the adsorbent and DB15 azo dye [49]. This was observed in membrane forms immobilized with Fe 3 O 4 NPs ( Table 6).…”

Polyaniline nanofibers as highly effective re-usable adsorbent for removal of reactive black 5 from aqueous solutions

“…The same method has already been adopted [37] by researchers to verify the favorability of a Langmuir type of adsorption. A comparison of the Langmuir maximum adsorption capacity (q m ) for the removal of RB5 by different adsorbents reported earlier in the literature is summarised in Table 2 [16,18,[38][39][40][41][42][43][44][45]. It is observed that the RB5 adsorption capacity of the PANI NFs is significantly higher than most of the reported adsorbents.…”

Experimental Study to Remediate Acid Fuchsin Dye Using Laccase-Modified Zeolite from Aqueous Solutions

“…The adsorption of AFD onto LMZ was also evidenced by an increase of the K, Ca, Ti, Fe, and Cu signals in the EDX spectrum of dyeloaded LMZ since these elements were present in the dye structure. It was also noted that the intensities of the Na, Si and Al peaks in the EDX spectrum of zeolite decreased after AFD adsorption [6]. This may be regarded as an ion exchange mechanism in addition to other possible interactions.…”
