Kinetics of absorbing fluorine about absorbent of ICOH bone was studied. The re suits showed. absorbed velocity is good in keeping with first kinetics equation
which is lnc=—3. 93 ×10-3t+0. 809 (r=0.975);maximum absorbed quantity is 248μg/g
Langmuir absorbed isotherm equation is c/(x/m)=c/248+1.09×10-3(r=0.9903).
