5. A method to calculate quantitatively the adsorption volume or adsorption space of per mass of adsorbent derived from both the adsorbed molecule volume and the maximum adsorbance of a solute in an adsorption isotherm under a given experimential condition is presented firstly for a solid / liquid adsorption system of the solute in a dilute aqueous solution . this method is suitable for not only mono - layer adsorption , but also mani - layer adsorption and micelle adsorpion of surfactant constructed by hydrophile and lipophile groups . therefore , the surface concentration of the adsorbate , cs , deduced from the adsorption volume is possessed of the meaning of true concentration , and the value of the patition coefficient of the adsorbate between solid and liquid phass , p , attained by the cs and the c , solution concentration of the adsorbate , can be accurate . the foregoing a set of calculations are presented for the solid - liquid adsorption systems consisted of the wool fiber and separately dodecyltrimethyl - ammonium bromide ( dtab ) and hexadecyltrimethyl - ammonium bromide ( ctab ) in this paper . this provides a strong basis for adsorption thermodynamic investigation of adsorbate
