Ulexite (Na2O·2CaO·5B2O3·16H2O) is one of the most important raw materials for boric acid,
synthesized by dissolving the ore in an acid solution. Since ulexite ore was
dissolved in a phosphoric acid solution, the
final solution included boric acid (H3BO3), sodium
dihydrogen phosphate [NaH2PO4],
and
calcium
dihydrogen phosphate [Ca(H2PO4)2].
The presence of several ions in the solution causes separation
problems for boric acid. This
study includes a special separation step to increase the purity of the
boric
acid that is synthesized
from the dissolution of ulexite ore in phosphoric acid.
For this
purpose, calcium ions in the
final solution were removed using Dowex HCR-S cationic ion exchange resin. Additionally, the Taguchi
optimization method was employed to monitor the removal of calcium ions
.
The design of
experiments
included an orthogonal array
technique in L9 array for three parameters with three different
values; reaction temperature (12 oC, 25 oC, 40 oC),
stirring rate (250 rpm, 300 rpm, 350 rpm), and the amount of resin material
(10% wt., 30% wt., 50% wt.). The results of the calculations revealed that the
optimum values of temperature, stirring rate, and amount of resin are 12 oC,
350 rpm, and 50% wt., respectively. The amount of calcium removed under optimum
conditions was found as 79.49%.
