Additions of acetic acid and sodium chlorite were continued at 2 h intervals
until the wood became white, which in this case required
11 additions of acetic acid and sodium chlorite. The wood
was washed twice during the treatment and at the end
with minimum of 60 L of deionized water. Before washing,
the wood was left in the acidified chlorite solution for 12 h
at 70–75 C. The total treatment time of the wood flour in
acidified chlorite solution was 58 h.
