An evaluation of Linear, Freundlich and Langmuir equations on both accuratity and stability indicates that the Linear equation is the best. Sorption of p nitrophenol to sediment is dominated by the partition of solutes to sedimental organic matter. The influences of temperature on sorption of p nitrophenol to sediment was also investigated. The sorption parameters of thermodynamics,Δ H =-7 8?kJ·mol -1 , suggest that the sorption behavior is dominated by dispersive force.

The scale inhibition mechanism of PESA was proposed on the basis of characterization of transformation of calcium carbonate crystal by means of X-ray Diffraction and scanning electron microscopy. The effect of temperature on corrosion inhibition efficiency of PESA was investigated and the Bockris substitution model is proposed to study the thermodynamics of inhibiting process of PESA. The calculation results show the adsorption of PESA on carbon steel is a spontaneous exothermic process with the increase of entropy.
