Abstract :
This study aims to determine the lemon juice (Citrus limon (L.) Osbeck in reducing levels of heavy metal copper. Lemon juice is carried out phytochemical screening tests to determine secondary metaboit compounds that can be used to reduce levels of copper metal. Determination of copper content by squeezing lemon was added with a copper simulation metal of 10 ppm which was read by the Atomic Absorption Spectrophotometry method at a wavelength of 324.8 nm.The determination of copper reduction was carried out using a lemon juice concentration series of 10%, 20%, 30%, 40%, 50%, 60% and 70% The results showed that lemon juice (Citrus limon (L.) Osbeck positively contained active compounds of citric acid, alkaloids, saponins, and steroids and produced an average decrease in the level of copper metal after giving lemon juice with a concentration of 10% of 0.69 (% KV 0.42%), 20% concentration of 1.80 (% KV 0.42%), 30% concentration of 11.85 (% KV 1.28%), concentration of 40% of 33.57 (% KV 0.33%), 50% concentration of 49.92 (% KV 0.86%), 60% concentration of 54.14 (% KV 0.69%) and 70% concentration of 64 .89 (% KV 0.30%). Lemon juice produces an average concentration value that can reduce copper up to 50% (EC50) by 55.8
