Abstract

Sand was obtained from the fractionation of Bijoypur soil of Bangladesh. Different advanced techniques such as SEM (Scanning electron microscope), LIBS (Laser induced breakdown spectroscopy), FT-IR (Fourier transform infra-red spectroscopy), XRD (X-ray diffraction) were used to characterize the physical and chemical nature of sand. The adsorptive property of sand toward methylene blue (MB) was also investigated in batch process. The SEM micrographs in different magnifications show that the surface of sand is heterogeneous in nature and the particle’s sizes are almost uniform (particle size ≥ 140µm). LIBS analysis confirmed the presence of Fe, Si, Ti, Cu, F, I, Tc, Ni, Pu and Na in sand. Sand fraction thus obtained was mainly quartz, which was supported by XRD analysis. FT-IR spectral analysis showed the presence of Si-O bond in sand. The adsorptive property of sand toward MB showed that about 24% ( 0.28 mg/g) of MB adsorbed on sand within 90 min. of contact time at neutral pH of solution and ambient temperature.
