ION-CHROMATOGRAPHIC INVESTIGATION OF BROWN-ALGAE (FUCUS-VESICULOSUS) OF THE GERMAN-ENVIRONMENTAL-SPECIMEN-BANK

An investigation of the inorganic anions and cations Cl-, HPO42-, NO3- , SO42-, NH4+, K+ and Na+ in brown algae collected from various locati ons in the North Sea and Baltic Sea is presented. Ion chromatography w as effectively used for the simultaneous determination of anions and c ations after extraction of the homogenized algae samples with deionize d water following the standard preparation technique of the German Env ironmental Specimen Bank (ESB). Acidic and enzymatic digestion was app lied to investigate the completeness of cell disintegration in the hom ogenized algae samples. Results obtained with brown algae clearly indi cate the influence of environmental pollution in the North Sea and the Baltic Sea.
