Malachite Green Adsorption

  1. Prepared Malachite Green (MG) Stock Solution
    • old Fisher bottle (oxalate salt, 95% dye content)
    • 0.00100 g ± 0.00003 g
    • due to static, some MG lost to spatula & bottom of dish (~90% recovered)
    • 500 mL HPLC water (vol flask)
    • 2.0 mg/L
  2. Cut 10%NaMT/PVOH Film
    • originally prepared by Karlena Brown & stored in HPLC water
    • used 15 mL PS falcon tube opening
    • 15mm diam x 1.39mm thickness = 0.33621 g (used for dye adsorption)
    • second piece = 0.37130 g (used for swelling/water absorption determination)
  3. Prepared Working MG Solutions
    • 0.2ppm, 0.5ppm, 0.8ppm, 1.1ppm, 1.4ppm, 1.7ppm by dilution
    • prepared by mass, assuming 1g/mL (100 g total)
    • stored in amber bottles & parafilmed (~200 mL of 2.0ppm remained)
  4. Equilibrium studies
    • 10 mL 2.0ppm solutions
    • 20 mL scintillation vials w/ mini-stirbars
    • 100mg of various clays & cut PVOH sample
    • Na-MT, HdPh3P-MT, Bu3HdP-MT, HxPh3P-MT, & HdMe3N-MT
    • HdPh3P-MT was most hydrophobic --> floated, with little suspended in water
    • Bu3HdP-MT & HdMe3N-MT were not finely ground
    • equilibrated 72 h
