Title: how to remove dichloromethane from aqueou s solutions (<10 ppm)
Post by: karl26 on September 17, 2007, 03:44:24 AM

Hi,


I need to remove dichloromethan from aqueous solutions (the quantity has to be < 10 ppm)

does anyone know a procedure which is suitable to work on 1-2 liters of aqueous solution ?

I have a lot of aqueou ssolution, so I can lose some. I can heat it as well.


many thanks


  ;)

Whit else is in there? You can use membrane filtration or distillation to get highly purified water, but if you just want to get rid of DCM while leaving other stuff in solution it would help to know what the other stuff was.
