Abstract
A study of the effect of added sodium tripolyphosphate (STPP) on oily soil removal efficiency in hard water showed that as the concentration of STPP increases, the water hardness at maximum oil removal efficiency increases and the sharpness of the oil removal peak is lessened. The value of maximum oil removal efficiency was not influenced greatly by the concentration of STPP. The action of STPP on oil removal efficiency in hard water was that of softening the water. The pH of various hard water/STPP/sodium dodecylbenzene sulfonate (0.1 wt. %) solutions had a maximum oil removal efficiency at 7.7.Keywords
