The multiple emulsion technique includes three steps 1) preparation of a primary oil-in-water emulsion in which the oil dispersed phase is constituted of CH2CI2 and the aqueous continuous phase is a mixture of 2% v/v acetic acid solution methanol (4/1, v/v) containing chitosan (1.6%) and Tween (1.6, w/v) 2) multiple emulsion formation with mineral oil (oily outer phase) containing Span 20 (2%, w/v) 3) evaporation of aqueous solvents under reduced pressure. Details can be found in various publications [208,209]. Chemical cross-linking is an option of this method enzymatic cross-linking can also be performed [210]. Physical cross-linking may take place to a certain extent if chitosan is exposed to high temperature. 

STEP 1 PREPARATION OP STOCK SOLUTIONS. Usually, stock solutions of the solid reactants are prepared in advance, since many depositions are normally carried out. The three reagents required are ... 

STEP 1 PREPARATION OF STOCK SOLUTIONS. The aqucous Cd solution is prepared as for CdS. As for CdS, the nature of the anion does not appear to be very important—the sulphate is commonly used. 

Step 1 Prepare known samples of analyte covering a range of concentrations expected for unknowns. Measure the response of the analytical procedure to these standards to generate data like the left half of Table 4-7. 

Step 2. During the evaporation in Step 1, prepare the ion-exchange column by placing a glass wool plug inside the column above the stopcock Close the... 

Step 1. Prepare duplicate 90Sr and89Sr solutions. Into each of four centrifuge tubes with 20 mL of deionized water, add 1 mL of 0.1 M HN03. Pipette 2 mL Sr carrier into each tube. Pipette 2 mL of yttrium carrier into each of the first 2 tubes. Into each of the first two tubes, pipette 1 mL of 90Sr diluted standard solution into each of the other two tubes, pipette 1 mL of 89Sr diluted standard solution. Stir well.
