Calibration Curves for Malachite Green Stock Solutions

  • After saving the data from the data print table with the correct wavelength range (200-800nm), the absorbance at 423 and 617 nm of malachite green were plotted against the concentrations 0.2, 0.5, 1.1, 1.4, 1.7, and 2.0 ppm using MS Excel. The trendline function of MS Excel was used to calculate the linear regression equation for the curves.

Cross-linking and Neutralizing Batch 3 Films

  • This assignment was delegated to Jacob Esenther. He performed the procedure as stated in the cross-linking protocol.
  • After the films were neutralized with the sodium bicarbonate solution, the films were suspended in distilled with the previous films synthesized in the same brown, nalgene jar.
