【Abstract】 The authors applied the scanning porosimeter and its attachment (The instrument is Quantachrome made of U.S.A) to study the apparent densities of the ion exchange resin and polymeric adsorbent. The values obtained by this instrument were duplicate. The average derivation was less than 1%. The authors also discuss the influence of the presure and temperature on the removal of gas and the experimental results.更多还原
