| Abstract The present work study the adsorption and photolysis of chlorobenzaldehyde in solution on the surfaces of Bentonite , Kaolin and Attapulgite. UV- visible spectrophotometer technique ,pH and conductivity have been used to follow the results,which showed a higher adsorption on kaolin surface than bentonite and Attapulgite. Rate of degradation reaction is 10.5 , 2.55 and2.1( mol/l.min-1 ) on kaolin,Bentonite and Attapulgite respectively. While the value of conductivity and pH were increased through adsorption process when bentonite surface used. Phtolysis processes for chlorobenzaldehyde showed higher rate of reaction in the absence of any and equal to 4.65 ( mol/l.min-1) .A kinetic study was carried out for the degradation of chlorobenzaldehyde different kind of clay . The results showed first order reaction and a relatively high rate of reaction kaolin 4.5, 4.5 and 3.45 ( mol/l.min-1) on kaolin,Bentonite and Attapulgite respectively and a short half life time ( 23.1,23.1 and 30.13 )min for the same surfaces . | ||
