    Colours play an important role in our life. Colour is a source of pleasure for everybody. Dyeing substances are used to impart colour on textile, plastic, leather, cosmetics, rubber, paper or any other material which we use in our daily life. Natural dyes were used till mid19th century. After that scientists started to developed dyes from chemicals. Synthetic dyes were cost-effective and easy to apply. Nowadays every product we use has been dyed with synthetic dyes. The problem withsynthetic dyes is that most of the dyes are toxic.Dyeing is always been a water-intensive process. So, industries are generating a large amount of contaminated water. This water is later released into waterbodies and has a bad impact on the aesthetic nature of the environment. In this research, a dye removal named adsorption is discussed. Adsorption is a popular method for waste water treatment and activated carbon is a very good adsorbent for this process. Forlarger industrial applications, AC is expensive. In current thesis, Tamarind wood derived Soft Coke was used as an adsorbent to compare the efficiency with commercially available activated carbon. Total 6 sets of samples of 2,5,10 & 20 ppm concentration (volume 10ml), MB were prepared. In the first four of them, CP was used as an adsorbent and for the remaining two samples AC with variable amount was used. After 3 hours of adding the adsorbent solutions were filtered with Whatman Filter Paper No. 1. The UV-Visible data of all filtered samples were recorded. With the help of the absorbance value of all the samples, the percentage dye removal was calculated. The results show that 0.10 gm CP is sufficient for dye removal from 10 ml of 2,5,10 & 20 ppm MB solutions. The efficiency of 0.10 gm CP and 0.01 gm AC was found to be similar. On comparing the price of both of the adsorbents it was concluded that CP can be used as an alternative to AC.
