ชุดทดสอบฟอสเฟต Tube Test (0.05 – 1.50 mg/L P (PO4-P) and 0.2 – 5.0 mg/L PO43- )

NANOCOLOR® ortho- and total Phosphate 1

Photometric determination of phosphate

DIN method: ammonium molybdate reacts with orthophosphate ions to form phosphomolybdic acid. This is reduced to molybdenum blue. For the determination of total phosphate, an acidic oxidation at 100 – 120 °C must preceed to detect poly- and organic phosphates. (Reaction basis according to DIN EN ISO 6878-D11).
