Ion-exchange reactions between acid mucopolysaccharides and various cations

Ion-exchange reactions between acid mucopolysaccharides and various cations.

In studies of cation-binding by acid mucopolysaccharides and the possible significance of these reactions in calcification processes, it has been shown, in cartilage, that the chondroitin sulphate component is solely responsible for the cation-binding capacity, that the cation-binding reactions are of the ion-exchange type and that different cations exhibit varying degrees of affinity for the c...

Ion Exchange Reactions of Clays

I t has been recognized for many ypars that many aspects of clay technolofcy including soil treatment and drilling nnul treatment must remain in an essentially empirical state until a basis for the understanding of ion exchange reactions is established. Much of the work on ion exchange reactions of clays in the i)ast has been directed toward establishing total exchange capacities or determining...

"Dueling" ESI: instrumentation to study ion/ion reactions of electrospray-generated cations and anions.

Novel instrumentation has been developed which allows for the sequential injection and subsequent reaction of oppositely-charged ions generated via electrospray ionization (ESI) in a quadrupole ion trap mass spectrometer. The instrument uses a DC turning quadrupole to sequentially direct the two ion polarities into the ion trap from ESI sources which are situated 90 degrees from the axial (z) d...

Ion exchange membranes and separation processes with chemical reactions

Recent research trends in the development of ion exchange membranes and their use in separation processes with chemical reactions are reviewed. Emphasis in research on the ion exchange membrane is trending toward analysis of micro-structure of the membranes and to development of new functionalized ion exchange membranes in response to industrial requirements. Separation processes with chemical ...
