This research aims to develop a field test kit for analyzing zinc ions. Based on the occurrence of zinc complexes with ligands of the time zone. Found that adding sodium bicarbonate to help maintain the stability of the ligand. Test series are all second bottle by bottle, the first solution is the liberated zones mixed with sodium bicarbonate in a solvent mixture propanol with acetone bottle 2 is sodium Flat Deck Silva sulfate in acetate. State buffer pH 5 and sodium thiosulfate. The color can be compared with the standard color of the two zinc concentration is highlighted in the concentration range of 0.1 to 0.5 milligrams per liter, and the colors in the concentration range of 0.5 to 5.0 milligrams per liter. This test kit can diagnose zinc ions at concentrations low. Correctly Not disturbed by other ions are stable, can be stored for up to three months in the cold and without light. Comparative analysis with technical analysis UV Visible spectroscopy techniques of chromatography and atomic absorption spectroscopy in the application. This analysis yielded no different.
