THE EFFECT OF VARIATIONS OF LEAD METAL SOLUTION PH VARIATIONS ON ADSORBENT FROM TIRTA MUSI WASTE MUD WASTE PALEMBANG

Abstract

Industrial waste can cause environmental pollution, one of which is solid metal waste.  Lead is a dangerous and toxic heavy metal that can cause damage to the surrounding environment. Liquid waste containing mercury in industry contains a mixture of chemical compounds that other This causes the pH of the solution in the waste to vary. Lead metal waste needs to be treated with method one of which is the absorption of waste using an adsorbent. To enlarge the pores, the adsorbent will be activated using a 2 M KOH solution with the selected adsorbent, namely the sewage sludge of PDAM Tirta Musi Palembang which contains PAC (Poly Aluminum Chloride) which can help optimize absorption. The level of metal degradation was analyzed using AAS with absorption parameters obtained 4 with an absorption capacity of 23 ,22 mg/g.
