29/2/2012, · Decolourisation is a result of two mechanisms (adsorption and ion exchange) and is influenced by many factors including dye/adsorbent interaction, adsorbent’s surface area, particle size, temperature, pH and contact time. Physical adsorption occurs when weak interparticle bonds exist between the adsorbate and adsorbent.
