mg/L), nitrat azotu (NO3‾-N)(0.81-5.29-1.58 ±0.09 mg/L) ve amonyum azotu (NO4 + -N)(0.0001-0.0097-0.0026 ±0.0003 mg/L). Arılı Deresi suyunun fiziksel ve kimyasal özellikleri, su kirliliği mevzuatında bildirilen kıtaiçi su kalite standartlarına göre incelendiğinde, yüksek kaliteli (Sınıf I) su standardında olduğu anlaşılmaktadır. Dolayısıyla Arılı Deresi sularının, sadece dezenfeksiyon ile içme suyu temininin yanında, rekreasyonel amaçlar, su ürünleri yetiştiriciliği ve diğer amaçlar için kullanılabilir su özelliğinde olduğu söylenebilir.

In this study, it was aimed to determine the effects of zeolite and bentonite on the ammonium adsorption at different temperatures. In this research three trial groups with 3 repetitions were created for three different water temperatures (18±0.1°C, 24±0.0°C, 27±0.0°C). Experimental groups were prepared by adding NH4+ amount of 10.5 mg/l in 2 liters of water. After that, zeolite, zeolite+bentonite and bentonite were added into the bottles as 10 gram per liter. Water temperature, pH and TAN (Total Ammonium Nitrogen) values were determined during the trial period. At the end of trial TAN values at 27 °C were recorded as 10.103±0.11 mg/l, 9.227±0.13 mg/l and 7.933±0.17 mg/l in zeolite, zeolite+bentonite and bentonite groups, respectively. At the end of trial TAN values at 24 °C were recorded as 10.027±0.17 mg/l, 9.282±0.15 mg/l and 8.336±0.15 mg/l in zeolite, zeolite+bentonite and bentonite groups, respectively. At the end of trial TAN values at 18 °C were recorded as 9.012±0.28 mg/l, 7.702±0.14 mg/l and 6.594±0.14 mg/l in zeolite, zeolite+bentonite and bentonite groups, respectively. Maximum ammonium removal capacity, qe, was found to be 0.50 mg/g in the bentonite (18 °C). The TAN values determined at 18 °C were statistically more significant (p<0.05) than the TAN values obtained at 24 °C and 27 °C.

Ammonia is an important nutrient in primary production, but high ammonia concentration is directly or indirectly toxic to many species of aquatic organisms. Ammonia and other toxic metabolites can be managed by adsorption and ion exchange. Zeolite is naturally occurring structured, aluminosilicate with high cation exchange and ion adsorption capacity. The purpose of this study was to determine the effects of zeolite on the ammonium adsorption at different particle sizes (0.075 mm, 3-5 mm) and adsorbent dosages (5 g/l, 10 g/l, 15 g/l) from aquatic solution. This research was conducted by trial groups with 3 repetitions during 330 min. Water temperature, pH, dissolved oxygen and ammonium values were measured during the trial period at regular intervals. Depending on the relevant literature, TAN (Total Ammonium Nitrogen) and adsorption efficiency were also calculated. This study values showed a decrease of TAN concentration in all the groups with increasing contact time. For different particle size and adsorbent dosage of zeolite, the best efficiency (44.1%) is determined at added 15 g/l and 0.075 mm zeolite group (P˂0.05). Our results revealed that zeolite might be used for ammonia removal in aquaculture. Su Ürünlerinde Doğal Zeolit (Klinoptilolit) ile Amonyum AdsorpsiyonuÖz: Amonyak, birincil üretimde önemli bir besin maddesidir, ancak yüksek amonyak konsantrasyonu, birçok sucul organizma türüne doğrudan veya dolaylı olarak toksiktir. Amonyak ve diğer toksik metabolitler adsorpsiyon ve iyon değişimi ile yönetilebilir. Zeolit doğal olarak oluşan, yüksek katyon değişimi ve iyon adsorpsiyon kapasitesine sahip bir alüminosilikattır. Bu çalışmanın amacı, farklı partikül büyüklüğü (0,075 mm, 3-5 mm) ve adsorbant miktarına (5 g/l, 10 g/l, 15 g/l) bağlı olarak zeolit ile sucul ortamdan amonyum adsorpsiyonunun sağlanmasıdır. Araştırma, 3 tekerrürlü deneme grupları üzerinden 330 dakika boyunca yürütülmüştür. Deneme süresi boyunca, düzenli aralıklarla su sıcaklığı, pH, çözünmüş oksijen ve amonyum değerleri ölçülmüş, TAN (Toplam Amonyum Azotu) ve adsorpsiyon verimi ilgili literatüre bağlı olarak hesaplanmıştır. Çalışma değerleri artan temas süresi ile tüm gruplarda TAN konsantrasyonunun azaldığını göstermiştir. Zeolitin farklı partikül büyüklüğü ve adsorbant miktarı için en iyi verim (% 44,1) 15 g/l ve 0,075 mm zeolit grubunda belirlenmiştir (P˂0,05). Sonuç olarak, zeolitin su ürünleri yetiştiriciliğinde amonyak giderimi için kullanılabileceği belirlenmiştir.
