摘要
Iron ore as possible adsorbent for metallic salts of fatty acid(M~(x+)-SFA) oils was investigated.Experimental constants from several kinetic models were used to interpret M~(x+)-SFA uptake.Mode of diffusion was also studied.Applicability tests for adopted models favors the Pseudo second order kinetics which presented high R~2 values > of 0.9; high precision or least qcal/qexp values of ratio within 1.0 for the K~+-SFA, Ca~(2+)-SFA and Al~(3+)-SFA sorption.The Pseudo second order equation also gave least values for the three error functions viz: 9.6×10~(-4) to 5.4×10~(-3), 3.1×10~(-2) to 7.4×10~(-2) and 4.6×10~(-3) to 2.5 ×10~(-3) for EABS, SSE and X~2 respectively.Multiple linearity presented by intra-particle diffusion plots is of three distinct stages of linear initial, linear intermediate and linear last portions.These stages are coupled with the nonpassage of lines through the origin being an indication that other diffusion models such as mass transfer or film diffusion exists and that the intra-particle diffusion is not the only rate factor controlling M~(x+)-SFA sorption.
