Abstract

Penelitian analisis gangguan ion Mn2+ dalam penentuan Fe(II) fenantrolin dengan pereduksi natrium oksalat dan hidroksilamin pada kondisi optimum menggunakan sprektofotometer UV-vis telah berhasil dilakukan. Kompleks Fe(II) fenantrolin memiliki panjang gelombang pada 511 nm untuk kedua reduktor. Pengukuran kurva kalibrasi pada reduktor natrium oksalat memiliki nilai koefisien determinasi (r2) sebesar 0,9989. Pada reduktor hidroksilamin hidroklorida kurva kalibrasi didapatkan nilai koefisien determinasi sebesar 0,9957. Ion Mn2+ dapat mengganggu analisa Fe(II) fenantrolin dengan menurunkan absorbansi besi. Pada reduktor natrium oksalat, Mn2+ mulai mengganggu saat konsentrasi Mn2+ 0,4 ppm dengan %recovery 93,45%, sedangkan pada reduktor hidroksilamin hidroklorida Mn2+ mulai mengganggu pada konsentrasi 2 ppm dengan %recovery sebesar 94,89%.

This study of Mn2+ ion interference in the determination of Fe(II) phenanthromline using sodium oxalate and hydroxylamin hydrochloride reductors has been successfully carried out. The optimum analysis performance was optimized using a sprectofotometer UV-Vis. The Fe(II) phenanthroline complex has a maximum wavelength at 511 nm for both reductors. The measurement of the calibration curve on the sodium oxalate reductor has a coefficient of determination value (r2) of 0.9989. The hydroxylamine hydrochloride reductor calibration curve has a value of the coefficient of determination of 0.9957. Mn2+ ions can interfere with Fe(II) phenanthroline analysis by lowering iron absorption. In sodium oxalate reductors, Mn2+ begins to interfere when the concentration of Mn2+ 0.4 ppm with %recovery of 93.45%, while in hydroxylamine hydrochloride reductors Mn2+ begins to interfere at a concentration of 2 ppm with %recovery of 94.89%.
