ABSORPTION OF COPPER (Cu) METAL SOURCE USING ZEOLITE ADSORBENT ON INDUSTRIAL WATER WASTE AT PT FERTILIZER ISKANDAR MUDA

Abstract

ABSTRACT

This study aims to examine the effectiveness of copper (Cu) metal absorption
contained in Industrial Wastewater using Zeolite Adsorbent. It is known that the
parameters contained in Industrial Wastewater are more dominant to heavy metals
where these contents are hazardous/toxicity in the event of pollution to the
environment. The tool used for the absorption of copper (Cu) content is an
adsorption tool with Zeolite adsorbent with a circulation time of 20, 25, 30, 35
and 40 minutes with an adsorbent size of 60/80 and 80/100 mesh which after the
adsorption process is carried out will produce Absorbance Data of Cu Product
Samples and Cu Concentration Decrease Data after the Adsorption process. To
analyze the sample using Atomic Absorption Spectrophotometry where the
sample will be tested which will produce Adsorption data results of Copper (Cu)
concentration in Industrial Wastewater, namely 0.8579 ppm or 7.7%, 0.7192 ppm
or 21.6%, 0.6073 ppm or 32, 8%, 0.4769 ppm or 45.8%, 0.4260 ppm or 50.9% at
60/80 mesh and 0.1523 ppm or 78.3%, 0.1329 ppm or 80.2%, 0.1162 ppm or
81.9%, 0.1116 ppm or 82.4%, 0.0616 ppm or 87.4% at 80/100 mesh and Contact
Time Graph Data of Copper (Cu) Concentration Decrease.
