| 摘 要： | INTRODUCTIONPolyacrylamide (PAAm) is one of the widely used organic flocculants for wastewater. Many studies wereperformed on modified PAAm such as partially hydrolyzed PAAm (HPAAm)[1], cationic PAAm[2], binarycomposition of anionic and cationic PAAm[3], HPAAm/anionic surfactant SDS complex[4], sodium alginate-g-PAAm[5], star-PAAm[6], HPAAm/aluminum sulfate mixture[7] and poly(acrylamide-co-acrylic acid)/inorganiccoagulant[8] to obtain more effective flocculants for the treat…

| Abstract: | The conductivity behavior of Al(OH)3-acrylamide hybrid polyacrylamide (hybrid PAAm) in distilled water was studied. A discontinuity phenomenon of the conductivity (k) versus concentration (c) curve of the hybrid PAAm in a certain concentration regime is found. This phenomenon is dependent on the molecular weight of the hybrid PAAm and on the particle size and content of the Al(OH)3 colloid in the hybrid PAAm. This phenomenon was accounted for assuming ionization of the hybrid PAAm. |
