| Abstract: | To study the absorption effect of ginkgo activated carbon,using static and dynamic absorption methods,the adsorption of part poisonous gas and two heavy metals(Pb,Cd) in waste water was studied.The results showed that the ginkgo activated carbon had good adsorb ability to the four gases of formaldehyde,benzene,chloroform and ammonia,and the adsorbing rate of formaldehyde reached to 140% formaldehyde,which was the highest.The adsorption of heavy metals on activated carbon was also fine,the absorptivity of Pb... |
