The melaleuca cajuput charcoal activated by steam is of the specific surface area of about 1000m2 g. The received activated carbon is used for further investigations to identify isotherm equilibrium curves kinetic characteristics of the adsorption of Sulfite Red S3B Sulzol Blue R-VL and Procion Yellow HE-XL dyestuffs. Langmuir s equations appear to fit well the experiments. For kinetic characteristics pseudo second order equations are found to fit better the experiments that is in agreement with other researchers. The investigations point out that the melaleuca cajuput activated carbon could be effectively used for textile waste water treatment. Keyword Activated carbon Melaleuca cajuput Waste water treatment. It has been found that melaleuca cajuput wood is a good material for activated carbon 1 . Nevertheless to identify the suitability of the activated carbon to practical uses it is necessary to study the adsorption characteristics of different species in corresponding media 6 8 . The investigations deal with some types of dyestuffs which are considered harmful to environment Sulfite Red S3B Procion yellow HE-XL and Sulzol Blue R. The suitability of the activated carbon to the contaminated components could be evaluated by the adsorption capability which is judged by isotherm curves and the adsorption speed which is judged by kinetics investigations. 2. MATERIALS AND METHODS Melaleuca cajuput activated carbon is self produced based on the procedure described in 1 . Its specific surface area is .
