| Abstract: | The solid-liquid separation of waste drilling fluid is a very important process in drilling industry.A high performance flocculant was prepared by chitosan(CS),methacryloyloxyethyl trimethyl ammonium chloride(DMC) and acrylamide(AM) with a previously prepared TiO2 sol by using the aqueous solution polymerization process.The influence of synthesis conditions and coagulant aid were investigated.The prepared CS-AM-DMC copolymer was characterized by Fourier Transform Infrared Spectroscopy(FTIR),Scanning Electro... |
| Keywords: | Chitosan grafted Terpolymers co-polymers Inorganic-organic flocculant Solid-liquid separation |
