Abstract EN
A relative ability of industrial samples of four phosphorus-free polymers (polyaspartate (PASP); polyepoxysuccinate (PESA); polyacrylic acid sodium salt (PAAS); copolymer of maleic and acrylic acid (MA-AA)) and of three phosphonates (aminotris(methylenephosphonic acid), ATMP; 1-hydroxyethane-1,1-bis(phosphonic acid), HEDP; phosphonobutane-1,2,4-tricarboxylic acid, PBTC) to inhibit calcium sulfate precipitation is studied following the NACE Standard along with dynamic light scattering (DLS), scanning electron microscopy (SEM), and X-ray diffraction (XRD) technique.
For the 0.5 mg·dm−3 dosage, the following efficiency ranking was found: MA-AA~ATMP>PESA (400–1500 Da)>PASP (1000–5000 Da) ≫ PAAS (3000–5000 Da)~PBTC~HEDP.
The isolated crystals are identified as gypsum.
SEM images for PESA, PASP, PAAS, and HEDP and for a blank sample indicated the needle-like crystal morphology.
Surprisingly, the least effective reagent PBTC revealed quite a different behavior, changing the morphology of gypsum crystals to an irregular shape.
The DLS experiments exhibited a formation of 300 to 700 nm diameter particles with negative ζ-potential around −2 mV for all reagents.
Although such ζ-potential values are not capable of providing colloidal stability, all three phosphonates demonstrate significant gypsum particles stabilization relative to a blank experiment.
