Hi everyone,
Can anyone explain the effect of temperature on adsorption for liquid and why ?

Hi,

Are you talking adsorption or absorption? Absorption is an exothermic process.

Adsorption is inversely proportional to temperature.  

For example, the desorption of activated carbon is performed using steam.

Thank you for your answer
Yes breizh i am taking about adsorption for gases the rate of adsorption increases with decrease in temperature but what about liquid ?
My answer is increase in temperature increases kinetic energy of a adsorbate molecule because of increased kinetic energy it becomes more easy to overcome weak van der waals force. Therefore for liquid adsorption rate increase with increase in temperature. Please correct me if i am wrong

Not... Temperature is inverted with the adsorption rates for gas in liquid. More temperature less gas into the liquid.

john, where did you read that (wrong) theory?
