PURPOSE: A test sheet for analysis of hexavalent chromium and a manufacturing method thereof is provided to easily analyze harmful hexavalent chromium. CONSTITUTION: A test sheet for analysis of hexavalent chromium comprises a filtering sheet; and a color-development component which emits a specific color by reaction with the hexavalent chromium; and additionally includes a releasing sheet. A manufacturing method of the test sheet for analysis of hexavalent chromium comprises a step of arranging solution which contains the color development component(S110); a step of impregnating the filtering sheet in the solution; and a step of drying the filtering sheet with impregnated sheet. [Reference numerals] (AA) Start; (BB) End; (S110) Prepare a solution containing a color development component(Acetone + 1,5-diphenylcarbazide); (S120) Impregnate a filtering sheet; (S130) Dry the filtering sheet(Filtering sheet + 1,5-diphenylcarbazide) |
