Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : A 2.0crn internal diameter I m long, axially-rotating horizontal glass tube, withfour axially located repeating hybrid magnetic units, is used as part of a flow-through.colloidal magnetic finity separation device. Each magnetic unit consists of analternating current solenoid surrounding the chamber followed by four azimuthallydistributed permanent magnets that rotate with the chamber. The separation isdemonstrated on a model feed system consisting of a mixture of I.Opm diameterbiotinylated latex beads (targets) and 9.7pm diameter non-functionalized latex beads(non-targets) at a 1:l number ratio. Two Feed flow rates of I2mUmin and 35mVminwere used until a total of 6OOmI of sample were processed for each. At the low rate weachieved capture efficiency 60 . a separation factor of 18.2 with 95 purity. For thehigher flow rate, the capture efficiency was 40 , the separation factor 18.6 with 87 purity-The same device also was used for removal of cadmium ions ب‌پ‍?om a cadmiumsulfate solution. Two arrangements for the magnetic units were used.
