Kemudian, larutan uji disuntikkan ke dalam tungku grafit. Melalui program pengeringan, abu, atomisasi dan pemanasan lainnya, komponen matriks yang ada berdampingan menguap dan dihapus. Pada saat yang sama, di bawah suhu tinggi dalam tahap atomisasi, senyawa timah didisosiasikan menjadi uap atom, yang menghasilkan penyerapan selektif dari garis spektral karakteristik yang dipancarkan oleh lampu katoda berongga. Di bawah kondisi penentuan optimal yang dipilih, penyerapan timah dalam larutan uji ditentukan oleh koreksi latar belakang.<\/p>\n<ol start=\"2\">\n<li>Lingkup Aplikasi<\/li>\n<\/ol>\n<p>Determination of Lead in Soil<\/p>\n<ol start=\"3\">\n<li>Referensi<\/li>\n<\/ol>\n<p>Digestion Methods: GB\/T 17141-1997; HJ 832-2017<\/p>\n<ol start=\"4\">\n<li>Detection Instruments<\/li>\n<\/ol>\n<p>Spektrofotometer Penyerapan Atom Tungku Grafit (Lampu Katoda Hollow Lead)<\/p>","protected":false},"excerpt":{"rendered":"<p>Method Overview The method of complete digestion with hydrochloric acid-nitric acid-hydrofluoric acid-perchloric acid is adopted to completely destroy the mineral lattice of the soil, so that the elements to be measured in the sample all enter the test solution.
