F–Fe/TiO_2 composite photocatalyst was synthesized by a facile one-step hydrothermal method and then characterized by XRD, XPS and UV–Vis DRS. The catalyst of F–Fe/TiO_2 exhibited the highest photodegradation rate for phenol as compared with pure TiO_2, F/TiO_2, Fe/TiO_2, F0.38–Fe0.13–TiO_2 and Fe(III)/F-TiO_2 under visible light irradiation. The simulated conditions of industrial phenolic wastewater including initial phenol concentration,visible light intensity, p H and different anions were investigated in the presence of F–Fe/TiO_2 photocatalyst. In addition, as expected, the F–Fe/TiO_2 photocatalyst displayed excellent stability, showing a potential industrial application for the treatment of phenolic wastewater.

多囊卵巢综合征(PCOS)占育年妇女的5%~10%,是女性不育的主要原因之一.不排卵,早期流产,妊娠后期并发症多是PCOS女性生殖力下降的主要表现.目前,有许多药物用于诱导PCOS患者排卵和受孕,其中枸橼酸氯米芬(克罗米芬)是一个口服、抵抗雌激素、促进垂体释放促卵泡生成激素(FSH),从而促进卵泡发育并排卵的简单而有效的药物。
