Study on the Colorimetric Determination of Tin in Soil and Rock
The phenylfluorone hexadecylpyridine bromide tin ternary complex photometry is a commonly used sample method for determining tin elements in high content rocks and soils.This article explores the experimental process of the phenylfluorone hexadecylpyridine bromide tin ternary complex photometry,including the optimization of reagent dosage,steps,and time control.Simultaneously conducting conditional experiments on interfering elements without masking agents facilitates the resolution of the effects caused by interfering elements during the measurement process.On the premise of ensuring data reliability,the influence of various parameters in the process of phenylfluorone hexadecylpyridine bromide tin ternary complex spectrophotometry on the measurement results was explored.The amount of experimental reagents and the use of other experimental parameters were accurately determined,which improved the accuracy and precision of experimental data,streamlined the measurement process,and reduced the interference caused by unnecessary factors.At the same time,the results of these basic studies can also provide some data reference for other methods to determine tin in soil and rocks.
