1.4]- is a complex ion that has not fully dissociated. 2. Au3+ is oxidizing and can react with ferrous ions.
If atomic absorption is used, I wonder if it will be more accurate?
You can use atomic absorption to eliminate interference; give it a try
Unfortunately, it is the inaccurate atomic absorption that causes the problem. After being diluted by half, the content actually increases. milligrams per liter.
