Taking bacterial cellulose (BC) as raw material, the paper prepared a modified bacterial cellulose sulphate adsorption material and carried out characterization analysis.It took the removal of Pb(Ⅱ) which is a typical heavy metal pollutant as the target,and investigated the impact of different reaction time,pH value of solution and reaction temperature on the adsorption behavior of Pb(Ⅱ). The results showed that the adsorption capacity of modified bacterial cellulose has been improved.The amount of adsorption on Pb(Ⅱ) by the material increases with the increase of pH and decreases with the increase of temperature. The adsorption process fits two stage reaction equation and Langmuir equation.
