Dendrimer modified magnetic nano-materials as water treatment agent in the oil field.

Using dendrimer with a special structure to coat magnetic iron oxide nano-particles to prepare water treatment agents of PF series of magnetic nano material modified by dendrimer, they have very good degreasing effect. At dosage of 50mg/L, oil removal rate can be up to 89.7%, far higher than 100mg/L Roman Haas with degreasing rate 66.6% .About suspended solids removal, water quality is clear and with no obvious suspended solids after the treatment of dendrimers based water treatment agents, while other agents suspended solids removal rate is low. This shows that the dendrimer-coated iron oxide magnetic nanoparticles greatly improved degreasing effect, not only played high adsorption role of magnetic iron oxide nano but also played bridging effect of dendrimer surface group.
