摘要: The effects of several phosphonic additives on the formation calcium sulfate scale metal surface in a flow system were investigated thoroughly using multiple pipe system. Their chemical structure, concentration and run time are to be main factors that influence inhibitory capability these anti-scalants. relationships between rate established. Langmuir adsorption isotherm is applied predict critical concentrations above which complete inhibition scaling will occur. efficiency order organic found as follows:EDTP > NTMP NDPA HEDP> NPDA, corresponds number phosphonate groups possess.
