Selective passage of hydrophilic nitrogenous organic materials through macroreticular resins

;
Prefiltration of natural water samples through XAD-8 and Tenax GC macroreticular resins removed, selectively, hydrophobic carbonaceous organic materials without significantly effecting hydrophilic nitrogenous organic substances. Hydrophobic carbonaceous adsorbates competitively decrease adsorption of hydrophilic materials. This phenomenon permits high recoveries of organic nitrogen while simultaneously removing humic material.
