Sularda bulunan nitratın adsorpsiyon yoluyla uzaklaştırılması

Bu çalışmada, adsorpsiyon yöntemi ile sulardan nitrat uzaklaştırma deneyleri yapıldı. Adsorban olarak sepiyolit seçildi. Üç farklı konsantrasyon ve pH değerlerindeki çözeltilerin kullanıldığı deneylerde bu dolgu malzemesi için optimum şartlar belirlendi. Elde edilen sonuçlar yorumlandı ve yönetmelikdeki sınır değerler ile karşılaştırıldı.

Removal of nitrate in water by means of adsorption

In this study, nitrate removing experiments in waters by adsorption were done. Sepiolite was selected as adsorbent. Solutions with three different concentrations and pH values were subjected to adsorption and optimum conditions were determined for this packing material. Obtained results were discussed and compared with limiting values in statute.
