Penurunan Kadar Tembaga (Cu) pada Limbah Cair Industri Elektroplating Menggunakan Cangkang Telur Ayam Potong Teraktivasi Termal

Abstract

Copper (Cu) heavy metal is produced from electroplating industry in its liquid waste. Eggshell has 7.000-17.000 pores and CaCO 3 that can be used as an adsorbent for adsorbing Cu. The purpose of this research was to analyze the differences of Cu levels between the liquid waste which was not given and which was given with broiler’s eggshell powder thermal activated at 600 0 C in concentration of 20 g/l, 25 g/l, and 30 g/l at 90 minutes contact duration. Type of this research

was a true experiment.
