Abstract

Waste could be found easily anywhere such as eggshells and rubbing-ash. Being a non-usable rubbish, These type of waste can be usefull in someways with a right treatment and deep research on compound material with in. The physical content from these waste utilized to be an adsorbent, it adsorbs a metal content e.g Mahakam river water sample. Main purpose of this research was based on benefical content from eggshells and rubbing-ash as their ability decreasing metal content. This study concluded experimentally using adsorbtion methods, a device such as Atomic Absobtion Spectrophotometer (AAS) was used to test the decreasing effect on logam content. The obtained data from testing process used to analyzed a metal concentration that disolved in water sample. This study results on decreasing metal concentration such as Fe and also Pb on Mahakam river water sample. Fe concentrat on these water sample shows decline rate from 1,5 mg/L to 0,11 mg/L given certain treatment adding eggshels powder. And also Pb content reduced from 1,69 mg/L to 0,24 mg/L indicate a little waste content from treated water sample. Inference from this study suggest addition of eggshells and rubbing-ash waste in form of powder had decreasing-effect on soluble metal content from Mahakam River water sample.

Abstract

The Mahakam River is a source of water for the people of Samarinda, East Kalimantan. However, Mahakam river water is not classified as quality water. As a result of industrial mining activities, river water is polluted by heavy metals such as Lead (Pb). These problems can be overcome by using the adsorption method to purify water. The adsorption method has become popular in adsorbing heavy metals contained in polluted water. The purpose of this study was to synthesize natural materials which are adsorbents for the heavy metal Pb. The materials used as natural adsorbents are household waste, namely ashes (AG), egg shells (CT), tea dregs (AT). Based on the results of the Atomic Absorption Spectroscopy (AAS) characterization test, data were obtained on the decrease in the concentration of heavy metal Pb in samples of Mahakam river water. The initial concentration of 1.8 mg/L became 0.24 mg/L (10 gr adsorbent AG) and became 0.17 mg/L (10 gr adsorbent AG+CT). While the use of AT adsorbent was applied to artificial waste with an initial concentration of 40 mg/L to 0.002 mg/L. Furthermore, according to data measurement, modeling was carried out using the Langmuir Isotherm and Freundlich Isotherm models to determine the adsorption capacity of tea dregs, eggshells, and ashes.
