Recyc PHP asked the Centre National en électrochimie et en Technologies Environnementales (CNETE) to test the absorption rate of sodium polyacrylate on various domestic fluids. Here are the results:
Absorption of edible domestic liquids:
- Beer: 77 g/g
- Sparkling water: 125 g/g
- Orange juice: 80 g/g
- Lemon juice: 11 g/g
- Tomato juice: 77 g/g
- Milk: 52 g/g
- Wine: 38 g/g
- Vinegar: 20 g/g
Absorption of domestic liquids of common use:
- Ammonia, acetone and alcohol isopropanol: unsatisfactory – SAP passes through filter
- Cleaner: no reaction
- Bleach: 18 g/g
- Painting in oil: results inconclusive. The viscosity of the paint prevents a good passage through the filter. Absorption is noticed on the SAP but it is less important. It should be noted that there is a loss of SAP due to the paint and its consistency.
- Water-based paint: 45 g/g
- Dishwashing soap: 45 g/g. The dishwashing soap has a high viscosity which then creates inability to thoroughly pass through the filter and leave only the SAP on it. Results inconclusive visually. The result is estimated.
- Varnish 13 g/g. With the varnish, the SAP seeks to agglomerate together more than other products.
