The effects of microwave power and sample quality on drying kinetics characteristics zirconia were studied. It is found that by increasing the decreasing mass, surface diffusion coefficient (Deff) appears to an upward tendency. corresponding value Deff at a mass 10, 20, 30, 40g are 1.849E-14, 2.443E-14, 3.210E-14, 3.278E-14 m2/s, respectively. 300, 400, 500, 600, 700W 1.270E-14, 1.784E-14, 2.61...

Affinity precipitation is a simple, single plate separation process in which the complex of a smart macroaffinity ligand with the target protein (from a crude broth) can be selectively precipitated by application of a suitable stimulus. Alginate is a copolymer of guluronic acid and mannuronic acid residues and precipitates with Ca(2+) ions. It was found to bind to pectinase present in a commerc...
