Super-absorbent Polymers in
Baby Diapers
By
Melissa Finch and Anne Shaffer
With help from Amy and Dr. Skip
Rochefort
The problem statement is to design and perform
a laboratory experiment to determine the properties of super
absorbent polymers (SAPs) in baby diapers.
The experimental method contained 2 tests. The
first test was to extract SAPs from six baby diaper brands plus
two industrial brands and saturate approximately 0.05g of each
sample, record and chart amount of water each sample will absorb,
and finally determine texture of different commercial samples and
compare with industrial brands. For the second test they had to
create gel beads using Keltone mixture and CaCl2 varying time
beads are in CaCl2, dehydrate bead in vacuum oven at 60 degrees
Celsius, and dehydrate beads using DI water.
RESULTS:
Charts comparing differant brands of diapers.
Charts of gel beads comparing concentration of beads and
time in CaC12
Selection of best baby diaper (in terms of SAPs)
