Thread: Increase level of zinc conc after treatment wif chitosan

Hi all,

I did a project recently to find out how chitosan would affect heavy metals conc in artificial wastewater. I have used zinc chloride along with distilled water. As many articles has stated, the level of conc for heavy metals would decrease after chitosan was added. However, the zinc conc increase after treatment by near 50%!
Is there any articles which i could refer to, so as to find out the cause of it?

Thanks
