Test composition, device and method for the colorimetric determination of phosphorus |
| abstract |
A unitized, one step test reagent composition, device and method is presented for the determination of phosphorus in various test sample fluids such as soil extracts. The invention is a modification of the Murphy and Riley methodology which utilizes a molybdate salt and a reducing agent to generate "molybdenum blue" in the presence of phosphate. In addition to the molybdate salt, the test reagent composition includes a chromogenic reducing agent which contributes to the color development and a solid buffer. The composition is preferably incorporated into a matrix such as paper for ease of handling. |
