Abstract

Bu çalışmada dp=2mm çaplı
tutuklanmış P. fluorescences
tanecikleri ile dolgulu kolon reaktörde, öncelikle 1 mg/L phosmet derişiminde
besleme akış hızının phosmet tüketim hızına etkisi incelenmiştir. Akış hızı
arttıkça film difüzyon direncinin azaldığı ve phosmet tüketim hızının arttığı
gözlenmiştir. En yüksek phosmet % tüketim değeri (% 99) en düşük akış hızında
(1.17 mL/dak) elde edilmiştir. Amaç yüksek dönüşüm yüzdesi elde etmek olduğu
kadar, yüksek phosmet tüketim hızıda sağlamak olduğundan 1.67 mL/dak akış hızı
daha sonraki denemelerde kullanılabilecek akış hızı olarak belirlenmiştir. Bu
akış hızında elde edilen phosmet tüketim hızı; 0.0096 mg/ g k.mo.sa, tüketim
yüzdesi ise % 97.5’dur. Dolgulu kolon reaktörde phosmet giderimi % 99 olarak
belirlenmiştir. Analizler tarımsal üretiminde yaygın olarak kullanılan
phosmetin çevreye olumsuz etkilerini azaltmak için alternatif olarak dolgulu kolon reaktörde
bakteriyel biyokütlenin kullanılabileceğini
göstermiştir.

Organophosphorus Pesticides Phosmet's Investigation of Biodegradation with Pseudomonas fluorescens in Filled Column Reactor

Abstract

In this study, the effect of
feed flow rate on phosmet consumption rate was investigated at a concentration
of 1 mg / L phosmet in a column reactor filled with arrested P. fluorescences
particles with dp = 2 mm diameter. It was observed that the film diffusion
resistance decreased and phosmet consumption rate increased with increasing
flow rate. The highest phosmet % consumption value (99%) was obtained at the
lowest flow rate (1.17 mL/min). Since the goal was to achieve a high conversion
percentage as well as a high phosmet consumption rate, a flow rate of 1.67 mL /
min was determined as the flow rate that could be used in subsequent trials.
The phosmet consumption rate obtained at this flow rate; 0.0096 mg / g k.mo.sa,
the percentage of consumption is 97.5%. Phosmet removal in the filled column
reactor was determined as 99%. Experiments have shown that fungal biomass can
be used as an alternative to reduce the negative environmental impacts of
phosmet, which is widely used in agricultural production.
