| Abstract: | With dilute sulphuric acid modified peanut shells as adsorbents,adsorption performance of methylene blue was investigated.The effects of time,initial concentration,pH value,and temperature on adsorption capacity were investigated.The results show the maximum adsorption of methylene blue was 94.53%,the maximum adsorption capacity was 18.53mg/g;The adsorption conforms to the equation of Langmuir;the modified peanut shells can be reused. |
