Sudden increase in P content in saltwater
Thread Content
The ICP analysis data for the 170 refined saline show that the P content has exceeded 3000 PPb in these past two days; it was practically negligible before. Could anyone tell me what might be the reason? How to deal with it?
Check both the raw salt and the water added from outside! Was phosphoric acid or phosphate added to the brine solution to remove calcium and magnesium?
As for the phosphorus content, I use hydroxide of strontium to remove magnesium and carbonate of strontium to remove calcium; the ratio of calcium to magnesium is 7 to 1, and membrane filters are used to remove the precipitates. Can the poster use the brine process on your end?
The original poster, could you share the manufacturing process used there? Thank you very much
Use phosphoric acid instead of calcium carbonate to remove calcium and magnesium. Is this confidential? .
What is the P content? You can use Chinese characters throughout the entire post; only the word representing the important information needs to be in letters. Do you have a problem with your brain, or are you just pretending?
My salt treatment process is the same as yours; the P level was too high but then returned to normal – it’s probably a problem with the analysis equipment
