Abstract: It was determined that the adsorption capacity of nano materials was higher than that of conventional adsorbents. In this study based on this topic, it is aimed to improve the performance of classical passive samplers for measuring high concentration of ammonia. Ammonia was measured at six different points in the industrial zone. The CNT addition sampler was also used in the measurements together with the conventional ammonia passive sampler. Thus, the effect of CNT addition on ammonia concentration was investigated. It was observed that the low CNT addition correlated with the conventional passive sampler but the correlation was decreased in the addition of high CNT.
