In this research work acid treated saw dust(ATSD) used to remove of dyes from aqueous solution. It is environment friendly & cheap. This research work has been carried out using Acid dye,1:2 metal complex dye, Acid-reactive dye, Reactive dye. The objective of work was how many dye separately removes from solution. Acid & 1:2 metal complex dye removed from auxiliary free aqueous solution. In similar dye concentration(gm/l) less ATSD removes acid dye than 1:2 metal complex dye. By Beers-lambert law we explained the deviation of ATSD solution from standard solution of T% & Wavelength curve.

For fulfil this demand there is establishment of a lot of textile factory in this subcontinent area. In case of increasing aesthetic property of cloth coloration various types of dyes are used in apparel. The presence of very small amounts of dyes in water (less than 1 ppm for some dyes) is highly visible and affects the aesthetic merit, water transparency and gas solubility in lakes, rivers and other water bodies (Mohammed et al., 2007). There are more than 100,000 commercially available dyes with over 7 x 10 5 of dyes produced annually worldwide processes (Ramaraju et al., 2014). However, these processes were very expensive and could not be effectively used to treat the wide range of dyes waste (Velmurugan et al., 2011). Many structural varieties of dyes exist, including acidic, basic, disperse, azo, diazo,
