How do you measure the hardness of discolored water?
asked 6 April 2017 asked by Misseau (690 points)
What is the source of the discoloration? If ferric hydroxide or algae is causing it, then you can first filter the water; since hardness is usually dissolved, the test result should not be affected.
Hi Misseau Can you give us more details about your question—specifically, what is the process in question and what is the discoloration caused by?
The water I want to analyze is discolored by inks; therefore, colorimetric analysis to determine water hardness is not possible.
OK, so we’re talking about industrial water here. Are you looking to determine water hardness as part of a special discharge agreement prior to releasing the water into municipal wastewater network?
A spectrometer has the abilith to discern concetration
Could you do a titration and measure the pH?
