Salvia officinalis leaf extractUV-Vis, FTIR, DLS, SEM, TEM, EDS, and TGAAgainst toxic dye shows significant catalytic activity in the degradation of CR dye.[223]
Gum acaciaUV-Vis, FTIR, TEM, and XRDUsed against toxic dye (4NP to 4AP).[224]
Gum arabicUV-Vis, TEM, and SWVThe technology was used to find MB in samples of river Water since its ability to recover values was beneficial.[225]
Acacia nilotica gum extractUV-Vis, FTIR, TEM, and XRDStudies have been carried out into the reduction 4NP to 4AP by NaBH4 (reducing agents) catalyzed using AgNPs.[226]
ChitinFTIR, XRD, XPS, SEM, and TGAUsed to 4NP reduced to 4AP in catalyst activity.[227]
