Sodium in adblue
« on: April 02, 2015, 07:12:54 AM »
I have a problem with sodium in Adblue (30% urea-70% water). Specification for sodium is 0,5 ppm and the ICP analysis finds from 3 to 10 ppm. I am thinking that the problem is in the water, if somebody can help...

Unfortunately i measure the Adblue when it is received by the consumer. It comes in plastic containers (contain 1 ton AdblUe) and is transported to buses' tanks through metal pumps.

What also worries me is that these boxes are in open space and i don't know if rain water enters.

Well, rain water should be sodium free. It will contain probably carbon dioxide or sulfur dioxide according the environment.  But any mineral water or tap water will contain some ions. I would recommend to get a sample directly after manufactering  and compare.
