Solute inclusion during progressive freeze concentration: A state diagram approach
نویسندگان
چکیده
We propose a conceptual model for progressive freeze concentration, which predicts solute loss through inclusion in the ice based on system's phase behaviour as illustrated state diagram. compare outcomes of sodium chloride, sucrose, and bovine serum albumin (BSA). For growth rates order 10−2 μm/s there was no chloride or but above this range, local super-cooling gives rise to freezing zone. In zone solution co-exist resulting uneven advancement causes inclusions. The that macromolecular solutions such BSA, will take place proposed mechanism.

Prevention of Initial Supercooling in Progressive Freeze-concentration.
A physical method is proposed that uses a cooling plate with many small holes to prevent initial supercooling in progressive freeze-concentration, and thus avoid serious contamination of the ice produced. The higher chance for ice nucleation of the water molecules in the holes due to the temperature gradient in the cooling plate resulted in the initial supercooling being completely prevented. A...
متن کاملMultiple impacts: A state transition diagram approach
Impact happens when two or more bodies collide, generating very large impulsive forces in a very short period of time during which kinetic energy is first absorbed and then released after some loss. This paper introduces a state transition diagram to model a frictionless multibody collision. Each state describes a different topology of the collision characterized by the set of instantaneously a...

متن کاملConcentration Polarization Phenomena during Dead-end Ultrafiltration of Protein Mixtures. the Influence of Solute-solute Interactions
The flux decline behaviour of some charged proteins and of binary mixtures of charged solutes during unstirred dead-end ultrafiltration has been studied. The mixtures consisted of the proteins bovine serum albumin, (BSA), cy-lactalbumin and/or lysozyme. Of special interest were a-lactalbumin and lysozyme because these proteins are physico-chemically identical, except for the sign of their charg...
