Study On The Effect Of Hydrophobically Modified Cationic Acrylamide Copolymers On Flocculation Properties

EpikIorohidrin, akrilamida dan trialkilamina digunakan untuk mensintesis monomer kationik hidrofobik 3-akrilamido-2 hidroksipropiltrialkilammonium kIorida dalam mana kumpulan trialkil adalah triheksilamina (AHPTHAC), trioKtiJamina (AHPTOAC) dan tridodesilamina (AHPTDAC). 1-6 mol % monomer kationik daripada setiap ktunpulan dikopolimerkan dengan akrilamida melalui pengkopolimeran larutan radikal bebas untuk menghasilkan poliakrilamida kationik yang diubahsuaikan secara hidrofobik dengan menggunakan ammonium persulfatl natrium hidrogen sulfit sebagai pemula redoks.\ud \ud Epichlorohydrin, acrylamide and trialkylamine were used to synthesize the hydrophobic cationic monomer 3-acrylamido-2-hydroxypropyltrialkylammonium chloride in which the trialkyl group was trihexylamine (AHPTHAC), trioctylamine (AHPTOAC) and tridodecylamine (AHPTDAC). 1-6 mol % of cationic monomer from each group was copolymerized with acrylamide via free radical solution copolymerization to yield the hydrophobic ally modified cationic polyacrylamide by using ammonium persulphate/sodium hydrogen sulphite as the redox initiator
