The principal cause of red tide and eutrophication is nitrate in waste water. High concentrations of nitrate in water can cause public health problems. The objective of this study is to remove the nitrate from nitrogenous compound by using adsorbents (Bio magmaⓇ, zeolite, chitosan resin)
Batch adsorption experiments were carried out to evaluate adsorption efficiency as time changes. Nitrate determined directly using UV detection with HPLC system, which consisted anion exchange column. Experiment with adsorbents confirmed efficiency of nitrate adsorption
among the three adsorbents. Using the MATLAB, we predicted aspect of adsorption and desorption according to retention time.
