Ma. Bacchi et Ead. Fernandes, EVALUATION OF THE WASHING SYSTEM EFFICIENCY IN SUGAR-CANE MILLS BY NEUTRON-ACTIVATION ANALYSIS, Biological trace element research, 43-5, 1994, pp. 663-668
The effectiveness of industrial washing operation in minimizing soil i
n sugar cane delivered to mills is evaluated. Instrumental neutron act
ivation analysis was the nuclear analytical technique chosen for this
work, with Fe, Hf, Sc, and Th selected as soil tracers. On the basis o
f differences between elemental concentration of integral and prepared
cane, that is before and after washing, the feasibility of the method
for evaluation of the washing efficiency is demonstrated.
