The reduce of the concentration of Fe and Co metal in liquid waste of batik and artificial waste have been done (investigated) using nanoparticles Fe3O4 absorbent. In an absorption method , Fe3O4 as an absorbent was mixed the liquid waste as the absorbed in a container. This research was used some of variables as pH was varied from pH 7 to pH 12, the mixing time (1, 3 and 5 hour), temperature (room, 90 � and 150 � ) and amplification. The finaly filtrate of artificial wate and liquid waste of batik and were measured absorbance used atomic absorption spectrophotometer. Based on the analytical result used SSA method, it was obtain that maximum absorption of Fe occurred at pH 12 and absorption of Co occurred at pH 9. Thus, nanoparticles Fe3O4 can readily absorb iron and cobalt in an alkali pH range. The results also showed that the long mixing time caused iron and cobalt can maximum absorbed. Iron and cobalt can optimum absorbed by mixing time at 5 hour with decreased percentage 99,9% at Co and 100% at Fe. At temperature varied, Co can optimal absorbed at room temperature with percentage 99,8% and Fe at temperature 150 � with percentage 100%. Amplification variable was done by repetition method of purification as much two times. Thus purification procces was done repeat caused Fe and Co metal can optimal absorbed. Thus, varied of pH, shaking time, temperature and amplification was influenced metal absorption at absorbent.
