ABSTRACT
Casuarina equisetifolia cone exhibited potential to remove methyl violet 2B dye from the aqueous solution. The
experiments were performed using batch method whereby parameters such as contact time, dosage,
temperature, pH, ionic strength and dye concentration were investigated. The kinetics of the adsorption process
was described using the pseudo-first-order, pseudo-second-order and Weber-Morris intraparticle diffusion models
with pseudo-second-order better described the adsorption kinetics and more than one diffusion mechanism may
be involved. The maximum adsorption capacity was determined as 63 mg/g, according to the Langmuir model.
