What ions are the membrane used to concentrate glyphosate afraid of?
Thread Content
Our company has a set of membrane separation equipment, which is mainly used to process the glyphosate mother liquor produced by the IDA method. There are some ions in the mother liquor, such as lead and arsenic. I wonder if these ions will damage the membrane?
Why is there lead and arsenic in your IDA process? The ions that general membranes are afraid of include: calcium, magnesium, aluminum, iron, etc., ions that can form precipitates or colloids, and oxidizing ions such as hypochlorite, etc. The pH of the IDA method glyphosate mother solution should be very low. At low pH, there will be some changes.
You are right as you said above. Lead and arsenic ions are not very oxidizing and should not have much impact. The main ones that are affected are oxidizing metal ions. The most feared ones are organic solvents. As long as the ions are not prone to precipitation, there will be no problem. The initial pH value of the IDA method glyphosate mother liquor is very low and should not be easy to scale. It will have little impact on the above-mentioned ions.
I wonder if many of you are familiar with Hangzhou Tianchuang? They specialize in glyphosate mother liquor concentrate. I wonder if their membranes are afraid of these ions? Also, I consulted their technical staff. They also can't be sure whether it has any impact. I think it should be no problem.
In principle, if it doesn’t precipitate, oxidize, or swell, there won’t be much of a problem.
Sometimes people don't pay attention to the red links under many posts. In fact, that is the answer. There are really many masters in Haichuan.
