Методика

Nano magnetic particles were prepared by chemical sedimentation. 500 ml of 1M aqueous solution of iron (II) chloride was placed into 250 ml of 0.1M aqueous solution of sodium dodecylsulfate (C12H25NaO4S), which is an anion surfactant, and then reacted under a nitrogen atmosphere for 12 hours. When an orange color suspension was formed, a salt was separated from the resultant by sedimentation at 2° C. The separated salt was subjected to water-washing with a 0.1 M aqueous solution of iron (II) chloride three to five times and then recrystallized in water held at 50° C., to obtain high-purity iron (II) dodecylsulfate salt (Fe(DS)2). Similarly, instead of iron (II) chloride, nickel (II) chloride and zinc (II) chloride were used in the reaction to obtain a nickel (II) dodecylsulfate salt (Ni(DS)2) and zinc (II) dodecylsulfate salt (Zn(DS)2), respectively. The critical micelle concentrations of these salts are shown in Table 1.
