Özet

Various methods can be used to remove ammonium from the water. In this study, the objective was the adsorption of ammonia by using harmless natural adsorbents. The toxic effect of ammonia on aquatic organisms changes depending on pH values. It was also focused on investigate the effects of the adsorbents on the pH in ammonium adsorption process.In this research, six trial groups (zeolite (Z:7 g.l(-1), 14 g.l(-1)), bentonite (B:7 g.l(-1), 14 g.l(-1)), zeolite+bentonite (Z+B:3.5 g.l(-1) + 3.5 g.l(-1), 7 g.l(-1) + 7 g.l(-1))) with 3 repetitions were created. At the end of the experiment, TAN, NH3 and pH values were calculated 7.15 +/- 0.23, 6.04 +/- 0.16, 8.59 +/- 0.20, 7.69 +/- 0.23, 7.61 +/- 0.16, 6.57 +/- 0.15; 0.28 +/- 0.01, 0.24 +/- 0.01, 0.40 +/- 0.01, 0.41 +/- 0.01, 0.32 +/- 0.01, 0.29 +/- 0.00; 8.10 +/- 10.01, 8.10 +/- 0.01, 8.18 +/- 0.01, 8.24 +/- 0.01, 8.13 +/- 0.00, 8.16 +/- 0.01 for 7 g.l(-1)Z, 14 g.l(-1)Z, 7 g.l(-1)B, 14 g.l(-1)B, 7 g.l(-1)Z+B, 14 g.l(-1)Z+B respectively. There were difference in TAN, NH3 and pH values between the experimental groups (p<0.05). Zeolite and bentonite are natural adsorbent used for removal ammonia in aquaculture. When the data acquired in the experiment are evaluated, it was determined that zeolite have the best values in the same conditions like temperature, initial pH, initial concentration, particles size and amount. An increase in the pH and decrease in NH3 values was also detected in 6 experimental groups, but it was determined that this increase did not exceed the optimum values for aquaculture.
