The goal of this research is to create ceria nanoparticles using a sol-gel method and aqueous Allium sativum (garlic) extract, as well as to investigate the use of the synthesised samples in Congo Red dye removal from water via adsorption and photo Fenton degradation. X-ray diffraction, Fourier Transform infrared spectroscopy, diffuse reflectance spectroscopy, scanning electron…

In a batch mode, the adsorption of an acidic dye, Methyl Orange (MO), onto non-viable blue green algal biomass, Oscillatoria sp., was studied in aqueous solutions with respect to operational parameters such as contact duration, adsorbent dose, pH, and temperature. Fourier transform infrared (FTIR) spectroscopy, elemental analysis, and scanning electron microscopy were used to characterise…

The ability of activated carbon (CSAC) and polypyrrole coated sawdust (PPy/SD) obtained from the fruit of Cordia sebestena’s gardening plant material to adsorb acid orange -7 from aqueous solutions was examined. The adsorption method is a viable treatment option, particularly if the adsorbent is affordable and easily available. Variations in experimental parameters such as pH,…

The dye methylene blue was tested for adsorption by the cesium Dawson heteropolyanion HCs5P2W18O62.16H2O. Adsorption is a critical step in heterogeneous catalysis. Adsorption can also be used as a separation method to eliminate unwanted colours from industrial waste. The first section is on adsorbent synthesis and characterization. The adsorption-related experimental parameters were then optimised. Finally,…

The adsorption of hen egg white lysozyme (HEWL) on adzuki bean charcoal powder (ABCP), which was made from adzuki bean waste by pyrolysis without combustion under a nitrogen atmosphere and subsequently comminution with a jet mill, significantly improved HEWL’s heat stress tolerance. Even at high temperatures, HEWL was well-adsorbed on ABCP. The remaining activity of…

Chitosan is thought to be an interesting raw material for membrane production because it has functional groups of –NH2 and –OH that are easily modified. The chitosan membrane has flaws such as low mechanical properties. To compensate for these flaws, silica is added during the chitosan membrane synthesis process to improve chitosan membrane stability. Plasticizer…
