Natural dyes are used in different fields like glass, textile, leather, food, pharmaceutical industries etc. Natural dyes have various advantages like anti-oxidation, anti-allergic, non-toxic etc. But application field of natural dyes is limited. There are about 450 plants in India used for dye extraction. In this research paper, their field of application, part of plants that can be used for dye extraction, types of colour they can produce are discussed. Plants used for dye extraction are used for making medicines also. Due to lack of proper knowledge and techniques, it is not possible to take complete advantage of these plants. There is not much knowledge about methods of dye extraction from dye yielding plants and their parts used for dye

    For this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.
