The nanoparticles were obtained by the co-precipitation method 5, 21-24.In 300 mL of distilled water, 19.7 g of FeSO 4.7H 2 O and 39.0 g of FeCl 3.6H 2 O were dissolved (molar ratio of ferric ion to ferrous ion in the solution of two). The solution was vigorously stirred (1000 rpm) and heated to 80 ºC.

When surfactant is dissolved in water, according to the principle of similar polarity and opposite polarity, its hydrophilic group and water phase attract and dissolve in water, while its oleophilic group repels water and leaves water.
Characterization and Chemical Stability of Hydrophilic
Given the prospect of using magnetic nanoparticles in the mining industry, this work aims to characterize hydrophilic and hydrophobic magnetic nanoparticles. Hydrophilic magnetic nanoparticles were synthesized by the co-precipitation method with no surface modification, while the hydrophobic nanoparticles were obtained by functionalizing the hydrophilic nanoparticles with oleic acid.

The paper analyses influences of the temperature and hydrophilic groups on micellar properties of ionic surfactants with 12-carbonic hydrophobic chains. The aim is to assess the impact of hydrophilic groups and temperature on thermodynamic parameters and micellization. This knowledge is indispensable for the formulation of new dosage forms. The method uses conductometric measurements.
