Slight colouration of water sources could make them unacceptable to consumers though it may not be toxic to the same degree. The source of such pollution lies in the rapid increase in the use of synthetic dyes. These wastes spoil the natural habitat of the aquatic species, the best practice for the removal of dyes and heavy metals is considered for the present investigation is Biosorption Hyptis Suaveolens powder is used for the removal of Tiatan Yellowdye from aqueous solution. The parameters investigated includes, agitation time, biosorbent size, pH, initial concentration of dye, dosage of biosorbent and temperature. The Kinetic study incorporated lagergren first order and pseudo second order models. The study also included thermodynamics and isotherms like Langmuir, Freundlich and Temkin. The experimental data was correlated for regression analysis and the data was very well fitted.
