Abstract

Polyaluminum nitrate sulfate comprises 5-5.6 wt.% aluminum, 2.4-3.2 wt.% sulfate, 14.5-25 wt.% nitrate and water to 100 wt.%. Polyaluminum nitrate sulfate (PANS) comprises 5-5.6 wt.% aluminum, 2.4-3.2 wt.% sulfate, 14.5-25 wt.% nitrate and water to 100 wt.%. Independent claims are included for the preparation of the PANS comprising either dissolving the Al-containing reagent in H2SO4 and HNO3 at 50-130 degrees C, neutralizing with a calcium-containing reagent and separating off the formed CaSO4 or reacting at 130-200 degrees C and 1-3 bar and removing the insoluble products.
