Manganese is an essential trace element of the human body, it can promote the body’s development and has anti-cancer effect. However, high levels of manganese in drinking water can cause water to color and precipitate, leading to adverse effects. China’s health standards have some restrictions on the manganese content in drinking water. In this method, manganese and salicylfluorone (SAF) - cetyltrimethylammonium bromide (CTMAB) are formed in the range of pH 8.6-6.6.
