Abstract
Riboflavin is one of the B vitamins and essential component of flavin
mononucleotide and flavin adenine dinucleotide. Riboflavin is yellow and naturally
fluorescent when exposed to ultraviolet light. In this project, adsorption of riboflavin
was analysed using Aspen Adsorption software. There are 3 condition that consider
performing this simulation which is initial flow rate (10, 20, and 30 mL/min at constant
bed height and initial concentration of RF, 2 cm and 50 ppm respectively), bed height
(changing the bed height 2 , 4, and 6 cm at constant initial flowrate and initial
concentration of RF, 10 mL/min and 50 ppm respectively), and initial concentration
varied the initial concentration at 50, 100, and 200 ppm at constant initial flow rate 10
mL/min and 2 cm bed height). Taking 303.15 K for the fixed temperature for all the
simulation. Breakthrough curve of riboflavin adsorption show shorter time taken to
reach the breakthrough point by increasing the initial flow rate and initial concentration
of riboflavin for both simulation and experimental. Otherwise, increasing the bed
height will give negative result on adsorption of riboflavin. The study of riboflavin
adsorption also being analysed by using three different model development ( Thomas,
Yoon-Nelson, and Adam-Bohart ). The result show Thomas Model and Yoon-Nelson
Model exhibit better performance than Adam-Bohart by analysing the R2
value.
