1.The results showed that 15-25mg of protein can adsorb on each gram of 0-methylhenylamino-agar beads after suction-dried the gel in pH5.5 buffer of 0.25mol/L KCL, 0.1mol/L phosphate at 4℃, the remaining activity of immobilized aspartase was over 90%.
2.Based on Langmuir adsorption curve of this matrix obtained by batch test method, its affini- ty capacity for endotoxin was 2. 0 mg per gram. The apparent dissociation constant between endotoxin and the adsorbent was 8. 1 ×10-10 mol/L. With a similar method, a ny1on 66 mi- crofiltration affinity membrane was prepared and its characteristics were investigated.
3.Under the conditions of temperature for 100℃, Modified each gram rice straw with 8.00mL benzyl chloride、 6.00mL de-ionized water、 8.00mL NaOH with the concentration is 6.0mol/L and 0.010g hexadecyl trim ethyl ammonium bromide respond 4 hours and weighting percentage of benzylated straw is 68.78%. .
4.As shown by experimental results,mercury was separated quantitatively by floation from aqueous solution containing 0.5 mL of 0.1 mol·L-1 NH4SCN solution and 1.0 mL of 1.0×10-2mol·L-1 CPB solution in a total volume of 10 mL including 5 mL of buffer solution to control the acidity at pH 5.0.One gram of solid NaCl was added to the solution.
