Pemanfaatan Cangkang Telur Puyuh Sebagai Pengikat Logam Berat Timbal (Pb) dalam Air

The lead (Pb) is an toxic heavy metal. It can dangerous the environment human health. Organic waste material has been used as adsorbend. The quail eggshell has level of CaCO3 (55.46%) which can be used to adsorb heavy metals such as Pb. The purpose of this study is to analyze the lead (Pb) that contacted with activated quail egg shell powder at a temperature of 800°C with a mass variation of the adsorbent 0gr/l (P0), 1.5g/l (P1), 3.5g/l (P2) and 5.5g/l (P3). They contacted with water that contain Pb, then stired using a Jar Test at speed of 250 rpm in 10 minutes let stand for 30 minutes. This study is True Experiment with completely randomized design. Data were analyzed using One Way Anova test with α = 0,05. The result showed that there were differences between the control groups and the treatment groups (p-value < 0,0001). The most significant differences occur in group with activated quail egg shell powder of 5.5 g/1 had the highest decrease of other groups, with the percentage of 85.71%. The activated quail egg can adsorb lead (Pb) in the water.
