Analisis Kadar Fosfat Dalam Air Sungai Ngelom Kabupaten Sidoarjo Jawa Timur

Abstract: Fosfat merupakan senyawa kimia dalam bentuk ion yang dapat menurunkan kualitas perairan dan membahayakan kehidupan makhluk hidup. Penelitian ini bertujuan untuk mengukur kadar fosfat dalam air sungai Ngelom yang mengalir di Desa Ngelom Kecamatan Taman Kabupaten Sidoarjo. Penentuan kadar fosfat yang terdapat dalam air sungai dilakukan menggunakan metode spektrofotometri UV-Vis. Reagen yang digunakan dalam pengukuran fosfat adalah ammonium molibdat dan SnCl2 yang ditunjukkan dengan perubahan warna menjadi biru. … Show more

“…Next, the solution was stirred and allowed to react for 7 minutes. Then, the solution was put into a cuvette and the absorbance of the solution was read at a wavelength of 650 nm (Ngibad, 2019). Furthermore, the absorbance data of each standard solution was made a curve of the relationship between concentration and absorbance using ms. Excel so that the equation of the linear regression line y = ax + b and the value of the correlation coefficient (R 2 ) shows the linearity of the standard curve.…”

“…Pada kenyataannya, kandungan senyawa fosfat yang berlebihan akan membahayakan kelangsungan makhluk hidup yang bertahan di ekosistem tersebut. Kandungan senyawa fosfat yang tinggi dalam ekosistem air dapat meningkatkan pertumbuhan beberapa jenis alga yang mengakibatkan terhalangnya sinar matahari yang masuk ke perairan (Ngibad, 2019). Untuk beberapa merk detergen yang ada dipasaran komponen Builders selain berbentuk fosfat dapat berupa Asetat: Nitril Tri Acetate (NTA), Ethylene Diamine Tetra Acetate (EDTA), Silikat: Zeolit, Sitrat: Asam sitrat, namun penggunaan secara ekonomis belum digunakan secara umum.…”

“…Spektrofotometeri UV-Vis biasanya digunakan sebagai analisa kuantitatif daripada analisisa kualitatif [5]. Metode spektrofotometeri UV-Vis telah digunakan untuk analisis kadar Fe [6], [4], ammonium [7], dan fosfat [8]. Untuk analisis kadar besi, Beberapa senyawa pengompleks yang dapat digunakan adalah molybdenum selenit, difenilkarbazon, fenantrolin dan Alizarin Red S (ASR) [9].…”
