Effects of Cationic Polypeptide on CaCO3 Crystallization
The use of organic additives to improve microbial-induced carbonate precipitation (MICP) is a novel and innovative idea. This study is the first to address the effects of the cationic biopolymer polylysine (poly-Lys) on CaCO3 crystallization and sand solidification by MICP. CaCO3 was precipitated with and without poly-Lys by hydrolysis of urea by using ureolytic bacteria, Pararhodobacter sp
The effects of different types of anionic polyacrylamide (PAM) on crystallization behavior of precipitated calcium carbonate (PCC) prepared via carbonation using calcium hydroxide and carbon dioxide gas. The percentage of aragonite phase increased higher reaction temperature. The use of anionic PAM resulted in the formation of larger PCC aggregates than in the case of PCC crystallized without
Effect of cationic polyacrylamide on precipitated calcium
Effect of cationic polyacrylamide on precipitated calcium carbonate flocculation: Kinetics, charge density and ionic strength Abstract. We quantified the adsorption kinetics of cationic polyacrylamide (CPAM) of three charge densities but constant molecular weight and their effects on the dynamics of a polydisperse calcium carbonate (CC
The effect of polymer adsorption kinetics and ionic strength on the dynamics of particle flocculation was quantified using a model system consisting of precipitated calcium carbonate (PCC) and cationic polyacrylamide (CPAM) at a low shear rate. All early flocculations detectable by a photodispersion analyzer (PDA) happened in nonequilibrium polymer adsorption regimes.
Effect of cationic polyacrylamide adsorption kinetics
The effect of polymer adsorption kinetics and ionic strength on the dynamics of particle flocculation was quantified using a model system consisting of precipitated calcium carbonate (PCC) and cationic polyacrylamide (CPAM) at a low shear rate.
Effects of Anionic Polyacrylamide on Carbonation for the Crystallization of Precipitated Calcium Carbonate Article in Crystal Growth & Design 15(4):1652-1657 路 January 2015 with 98 Reads
Correlation between flocculation and adsorption
The study of each stage of the flocculation process is essential to better understand and predict flocculation mechanisms. The adsorption of cationic polyacrylamide derivatives (C-PAM) onto precipitated calcium carbonate (PCC) has been investigated systematically as a function of the C-PAM characteristics including molar mass, chain architecture, and charge density.
Introduction. A mysterious hemorrhagic disease of cattle emerged in 2007 affecting solely newborn calves [].First named "blood sweating", "hemorrhagic diathesis" and "bleeding calf syndrome" it was finally designated "bovine neonatal pancytopenia" (BNP) at the Satellite Symposium of the European Buiatric Congress in 2009 [].During the last years an increasing number of calves were affected by
US Patent # 5,239,014. Cationic acrylamide polymers
Cationic acrylamide polymers and the applications of these polymers Abstract. This invention provides cationic acrylamide polymers which are highly effective as paper strength agents, drainage agents and suspension flocculants, and which do not show much temporal deterioration; it also provides a method of manufacturing said polymers wherein the manufacturing equipment is compact and can be
For bench-scale experiments, the wastewater effluent sample was concentrated in the laboratory by evaporation at 40 掳C to reach 4 cycles of concentration (CoC 4) as determined by 75% volume reduction, prior to use in a bench-scale water recirculating system ().However, it was discovered from preliminary tests that pre-concentrating the MWW resulted in a loss of mineral content due to
