    (2013-05-02) Fetriyeni, M.; Muhdarina; Nurhayati
    Clay as abundant natural products can be used for various things, one of which is a coagulant in water treatment. This research has been utilized Cengar clay as a liquid coagulant source. The liquid coagulant was made through extraction of the Cengar clay by using sulfuric acid solution with variation of concentration, temperature and extraction time. After measuring by Atomic Absorption Spectrophotometry methode, two liquid coagulants with the highest content of Al and Fe ions (mg/L) was found. There are (mg/L) : Al 28.118 and Fe 26.818 for liquid coagulant of Al>Fe type and Al 23.926 and Fe 34.993 for liquid coagulant of AlFe, the content of Mn (II) and Mg (II) in the peat water was reduced to 24.429 mg/L and 17.2 mg/L, similar to the liquid coagulant of Al
