Malachite green dye Preparation and Uses

Malachite green dye raises the concern about its use because it has toxic effects, so it must be treated before being given as a waste 13. Nanomaterials have been widely used for the removal of pollutants because they are effective adsorbent because of their large surface area and dispersion resistance 14 AbstractIn this review, the state of the art on the removal of malachite green dye from aqueous solution using adsorption technique is presented. The objective is to critically analyze different adsorbents available for malachite green dye removal. Hence, the available recent literature in the area is categorized according to the cost, feasibility, and availability of adsorbents In this paper, two kinds of metal-organic frameworks (MOFs), MIL-53(Al) and MIL-53(Al)-NH2, were synthesized. Then these MOFs were used to remove methylene blue and malachite green dyes from aqueous solution. Characterizations of MOFs were carried out by X-ray powder diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared (FT-IR) spectrometry, and zeta potential. -Specimen is heated to drive the dye (malachite green) into the spores.-Nonsporulating cells are stained with safranin.-Endospores appear green and other cellular features appear pink.• Differential staining highlights differences in bacterial cell walls in order to discriminate between classes of cells.-Examples: a
