Acetalization of ethyl acetoacetate with ethylene glycol using heteropolyacid H_3PW_(12)O_(40) supported on active carbon as catalyst
A method for evaluating the adsorbability of the active carbon composite filter is established.
The adsorbing agents such as molecular sieves, metal oxides, active carbons, etc sulfides removal are presented.
The adsorptive treatment of laboratory simulation chromium-containing wastewater by active carbon are researched.
It also studied adsorptivity of active carbon on which some of benzene hydrocarbon has been absorbed.
An outline of general position on active carbons from lignites is presented.
The result showed that the active carbon could control the influence of the harmful pigment.
