139. Solving a chemistry problem

When analyzing wastewater for beryllium content, a 100.0 ml sample was evaporated to 1.00 ml, and solutions of an acetate buffer solution and dibenzoylmethane were added. After introducing isoamyl alcohol into the solution, the organic phase was separated and the phosphorescence spectrum of the resulting beryllium complex was recorded at liquid nitrogen temperature. In parallel, the same sample was prepared with the introduction of 0.2 μg of beryllium and its phosphorescence spectrum was recorded; measured the heights of the peaks for both samples hx and hВе and obtained the following data:
Option 1
hВе, mm ...... 100
hx .............. 60
