Abstract

Telah dilakukan penentuan kadar Krom (VI) dalam air muara Sungai Baniir Kanal Timur Semarang dengan spektrofotometri UV - Vis. Pemisahan Krom (VI) dari unsur pengganggu dilakukan secara ekstraksi dengan menggunakan pereaksi kupferron dan pelarut kloroform. Fasa air hasil ekstraksi didestruksi dengan asam. Pengukuran serapan Krom (VI) dalam bentuk kompleks Krom (VI) dengan difenilkarbasida menggunakan spektrofotometer UV - Vis pada paniang gelombang 540 nm. Kadar Krom (VI) dalam air muara Sungai Bat-01r Kanal Timur Semarang berkisar antara 0,05 ppm eampai 0,5 ppm. Air muara sungai dengan Kadar Krom (VI) 0,05 ppm -0,5 ppm hanya dapat digolongkan sebagai sumber air golongan D. Determination of Chrome (VI) contained in water from estuary of Banjir Kanal Timur - Semarang with UV-Vis spectrophotometer has been done. Chrome (VI) was separated from its interference cations by using extraction method with kupferron. Acid destruction was done to aqueous solution and then complexed with diphenilkarbazide. The absorbance was measured by UV - Vis spectrophotometer. The Chrome (VI) contained in water from estuary of Banjir Kanal Timur River - Semarang was in range of 0,05 ppm - 0,5 ppm. The water was cl
