Hi all,

Do you all have method for maneb in water? I not able to find it. I only manage to find one is using acidify method of HCl to convert maneb become CS2. But the method no using maneb as sample testing. Can anyone advise on it?

Thanks

The indirect method where you detect CS2 I never got to work well. It also does not specify if you have Maneb, or Ziram, or other ethylenebisdithiocarbamate compounds present.

To separate Maneb from other carbamates you have to use HPLC, it does require some prep but doesn't seem any more complicated than the GC method.
