Adsorption is the
adherence to a surface of atoms, ions, or molecules from a gas, liquid, or
dissolved solid. This method produces an adsorbent film on the adsorbent's
ground. In the present study, Ulva intestinalis (formerly Enteromorpha
intestinalis) a member of Cyanophyceae collected form Covelong, Southeast coast
of Tamil Nadu was used for adsorbing methyl orange and phenol red. The results
showed that at 60 min of treating the phenol red dye with seaweed yield maximum
reduction (44%) of colour and in case of methyl orange 47.4% colour reduction
occurred after 60 min.
