UV VIS - Testing Beads' filtration ability

  • Continue with the previous procedure. Final results are already accumulated in the later lab notes.

Beads formation using 60% clay

  • Making the solution of 1.25 g PVOH, 62.5 mL of 3wt% clay, 15 mL 12.1M HCl
    • Mass of PVOH: 1.2502 g
    • Mass of clay: 1.25/4*6 = 1.875 g
    • Volumn of clay: 1.875*100/3 = 62.5 mL
    • Volumn of HCl: 15 mL
  • Repeat following this protocol
    • Higher stirring speed required
