Investigation of Heavy Metal (Lead) Removal from Aqueous Solution by Using Advanced Oxidation Process (Fenton)
Chemical Science International Journal,
Background and Aim: Undoubtedly, controlling the maximum entry of heavy metals into the food is one of the measures which should be taken into account in order to maintain the food consumers' health and achieve the food safety. The sensitivity and importance of this issue are doubled due to the irreparable, acute and chronic complications of heavy metals which are classified according to the effects on the nervous system until the carcinogenesis in the human body. On the other hand, this issue is significantly important since these metals differently enter to crops such as tea, water, and rice and generally the food and beverage that are widely consumed. Therefore, the aim of this study is to remove heavy lead metal from aqueous solution by Fenton method. This study is an experimental study. The samples are synthesized in a collection of laboratories at the Faculty of Health, and the pH parameters, contact time and lead elimination rate and the optimal Fenton ratio are investigated. Results are analyzed using SPSS software and Charts are plotted by excel. The results showed that the best pH for removal of lead 5 and its best concentration is 30 mg/ L, and the optimal Fenton ratio is 1 to 5, as well as the best contact time for removal of lead from aqueous media for 10 minutes. The present study showed that the pH factor, contact time, Fenton concentration and lead in all four were effective in removing lead from aquatic solution.
