We've encountered some problem in the results of our study. The results of our study is that the lower the zeolite loading the higher the percentage removal of nitrates. Other shows the opposite, I haven't seen any result of the study same as ours.
Hello Kimverly,
unfortunately I do not fully understand your question. What kind of "loading" of your zeolites do you mention? Is your zeolite loaded with a metal ion? Or is it (ore)loaded with nitrates before you use it for nitrate removal? Or do you think of the modul (Si:Al ratio) of the zeolite?
Hello Mr. Thomas Simons,
Thank you very much for noticing my question.
As for the zeolite loading, we mean here the amount of Zeolite that was added to our solution. Our study was to determine the effects of pH, initial concentration and the amount of zeolite on the removal of nitrates from our synthetic wastewater using rice-husk derived zeolite. Based on our results, as the amount zeolite increases the percent nitrates removal decreases. Also, on a small amount of zeolite,as the pH is increased the removal of nitrate decreased. And on a high amount of zeolite, as the pH is increased the removal of nitrate increase.
Is there any factor that affects our study?
Thank you very much!!!
Ok, now I have got your experiment.
Surprising result.
But I think it is explainable with the complex absorbent behavior of zeolites. In the attached paper, they claim a adsorbent behavior of zeolites in nitrate removal, which is dependent from many factors. Not only a lingered equilibrium time, but as well a coadsorption of several other ions (especially cations).

Thank you very much Mr. Thomas Simons. This is really a great help in our study.
