| A magnetic susceptibility technique is applied to find the effects of a wide range of parameters on the stability and transport of the nanoparticle suspensions. First section of the study is related to stability of nanoparticle suspensions with particular emphasis on determining an optimum nanoparticle suspension recipe. The parameters considered included sonication time, sonication power, type of dispersants, dispersant concentration, nanoparticle concentration and applied magnetic field.;In the second part of the study, the transport and retention of the nanoparticles in non-metallic horizontal flow cell containing porous medium were examined while using various nanoparticle suspension recipes. Furthermore, effects of a number of parameters such as permeability, matrix type, flow rate, suspension recipe type etc. were also observed. Based on the findings of the study, an empirical method of finding optimum suspension recipe has been proposed/ suggested, which could be further improved by incorporating more factors affecting stability of nanoparticle suspensions. |
