CALCIUM CARBONATE GROWTH MODIFICATION BY CONSTITUENTS RELEASES FROM POROUS CELLULOSE FILTER MEMBRANES

Filtration of a suspension of calcium carbonate (CaC0(3)) or other inorganic solutions are often part of the methodology for recovering crystals during biomimetic mineralization experiments performed by various procedures. However, the use of cellulose filter membranes (FM) may cause a problem in in...
