In this research, initiated (activated) carbon (AC) was formulated from rubber seed shell biomass, infused with ammonium chloride at a temperature of 500 °C for 2 h. The activated carbon was characterized by its functional groups, thermal stability, surface morphology, and elemental identification by using FTIR, TGA/DTA, and SEM/EDAX. Additionally, the AC remediation strength was assessed with dye (Congo Red) under various parameters like dosage and pH; and the Langmuir and Freundlich adsorption isotherm prototypes were used to evaluate the utmost uptake (qmax) of Congo Red by the adsorptive material. The maximum dye adsorption capacity was achieved at 24.35 g/L and fits well in the Langmuir isotherm model. Therefore, the findings of this research reveal the possibility of utilizing rubber seed shell biomass as economical and competent r...

Synthetic dyes are commonly used for dyeing and printing in a variety of industries. The traditional methods for the removal of heavy metals and dyes from wastewater are chemical precipitation, ion exchange, adsorption, membrane processes, and evaporation which require high capital investment and running costs. Activated carbon prepared from agricultural wastes and its by-products are good alternative sources for adsorption because they are low-cost, renewable sources with high carbon, volatile contents, low ash, and reasonable hardness. The preparation means of activated carbon are physical and chemical methods. The important advantages of chemical activation over physical activation are the process that can be accomplished even at lower temperatures and the yield obtained in chemical activa...

The as prepared Ti-CdSe and mere CdSe nanoparticles were characterized using XRD, UV, FTIR, TGA, SEM and TEM analysis. TEM micrographs confirm the synthesized samples are in nanometer regime. The insertion of Titania onto CdSe lattice was confirmed by XRD and SEM-EDAX analysis. The absorption spectrum of Ti doped CdSe nanoparticles showed blue shift (lower wavelength) than mere CdSe. Ti-CdSe nanoparticles have greater thermal stability than mere CdSe nanoparticles. The photocatalytic activity of the Ti-CdSe nanoparticles photocatalyst was determined by degrading a MB dye under solar light irradiation. Ti-CdSe nanoparticles maintain high photocatalytic activity under solar light irradiation in comparison to mere CdSe nanoparticles. Low electron-hole pair recombination with increased efficiency was observed...

These Cd-TiO2 have been characterized by various optical and techniques. They have been exhibited by X-ray diffraction, scanning electron microscopy, ultraviolet spectroscopy, and infrared spectroscopy. The structures of the various XRD patterns indicate that the product has a structure. The particle size of Cd-TiO2 is 35nm. The SEM images confirm the spherical appearance of the sample.

The stem extract acts as both reducing and capping agent. The synthesized Copper and Lead nanoparticles were confirmed by the change of colour after addition of stem extract into the Copper Sulphate and Lead Sulphate solution. The biosynthesized Copper and Lead nanoparticles were characterized by using UVVisible analysis, X-ray diffraction analysis (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray analysis (EDX). From UV-Visible analysis, Copper and Lead nanoparticles shows the characteristic absorption peak at 208nm and 239nm. From the XRD, it was found that the average particle sizes of both nanoparticles were found to be 3nm.
