ABSTRACT

 

Biosorption processes have attained great importance as an environmental point of view that they can remove toxic compounds from industrial waste water. Many industries use dyes to colour their products and discharge their waste in water which is harmful for aquatic life. Adsorption processes provide an attractive alternative for the treatment of coloured waters. Methylene blue adsorption on moss has been done using visible absorption spectroscopy. Different pre-treatments, protonation and chemical cross-linking with CaCl2 or H2CO3 have been tested in order to improve the stability as well as adsorption capacity of the moss biomass. Pretreatments gave different adsorption results and it was found that a particular pre-treatment can increase adsorption capacity of biomass. The results have shown that this type of material has a high adsorption capacity for methylene blue dye and moss was found useful as low-cost biosorbent in waste water treatments.
