Bromine content in some seaweeds of Goa (Central West Coast of India)

Abstract

Nineteen species of seaweeds from the coast of Goa were examined for their bromine content following the spectrophotometric method involving ashing with Na@d2@@CO@d3@@, oxidation of bromide to bromine with chloramine-T and measuring the absorbance in chloroform at 400 and 650 nm. The bromine content, on a dry dry weight basis, varied from 0.024 to 0.024% for the green algae, from 0.020 to 0.400% for the algae, and from 0.015 to 0.054% for the brown algae. Only two species @iChondria armata@@ and @iCodium elongatum@@ showed relatively high bromine contents 0.400% and 0.247% respectively. A large fraction of the bromine in these species appears to be organically bound
