On the other hand, fulvic acids (C 12 H 12 O 9 N, minimum formula disregarding sulfur) have a higher percentage of oxygen and excellent solubility even in very ,acidic, media. Due to their intermediary structural and chemical properties, humic acids (C 10 H 12 O 5 N as minimum formula) are extracted in diluted alkali solutions and present poor solubility in diluted acid [ 2 – 4 ].

Solar photocatalysis by the TiO 2 /Fenton method improved the performance of the photocatalyst at neutral pH for petroleum ,wastewater, without the need to adjust the pH during this treatment. Under ,acidic, conditions, the solar photo-Fenton process is more efficient than solar TiO 2 photocatalysis while it is less efficient under alkaline conditions.
