<\/a>Prinsip dan Aplikasi Penganalisis COD<\/h2>\n

Cod ialah indeks menyeluruh yang biasa digunakan untuk menilai tahap pencemaran air. Bahan pengurangan dalam air ialah pelbagai bahan organik, nitrit, sulfida, garam ferus dan sebagainya, tetapi yang utama ialah bahan organik. Oleh itu, Permintaan Oksigen Kimia sering digunakan sebagai ukuran jumlah bahan organik dalam air. Semakin tinggi Permintaan Oksigen Kimia, semakin tercemar air dengan bahan organik.<\/p>\n

Prinsip: sampel air, kalium dikromat, larutan perak sulfat dan asid sulfurik pekat dicampur dan dicernakan pada suhu tinggi, pencernaan suhu tinggi, penentuan sampel berdasarkan penyerapan kromium trivalen daripada kalium dikromat yang direduksi, nilai peningkatan penyerapan kromium trivalen adalah berkadar langsung dengan nilai COD, dan penyerapan kromium trivalen ditukar kepada nilai COD.<\/p>\n

Senario aplikasi utama merangkumi pemantauan air hujan dan air kumbahan perusahaan, pemantauan kandungan Analaiser COD dalam rangkaian paip perbandaran, stesen pam, air bawah tanah, air sungai, air tasik dan air laut.<\/p>","protected":false},"excerpt":{"rendered":"
