ABSTRAK Telah dilakukan penelitian tentang analisis tembaga dalam air sumur. Tujuan dari penelitian ini untuk menetapkan kadar tembaga dalam air sumur. Analisis menggunakan metode spektrofotometri serapan atom (SSA) dengan destruksi basah. Panjang gelombang untuk pengukuran tembaga adalah 324,8 nm. Hasil analisis menunjukkan bahwa logam tembaga pada semua sampel tidak terdeteksi. Hasil validasi metode analisis yang telah dilakukan meliputi akurasi, presisi, dan linearitas (0,2–1,0 ppm) memenuhi persyaratan yang ditentukan. Persamaan regresi linear kurva baku y = 0,034 x–1,76 . 10 -3 dan r = 0,998. Kata Kunci: analisis tembaga, air sumur, spektrofotometri serapan atom (SSA). ABSTRACT It had been done research about analysis of copper in ground water. The purpose of this research was to determine levels of copper in ground water. Analysis using atomic absorption spectrophotometry (AAS) method with wet destruction. Measurement wavelength was 324.8 nm for copper. The analysis showed that the concentration of copper metal was not detected in all samples. The results of the validation method of analysis has been conducted include accuracy, precision, and linearity (0.2 to 1.0 ppm) to meet the specified requirements. Standard curve linear regression equation y = 0.034x-1.76.10-3 and r = 0.998 Keywords: analysis of copper, ground water, atomic absorption spectrophotometry (AAS).References
