马铃薯Cr元素吸收实验：干燥处理对光谱采集的影响

14个马铃薯样品分别浸泡在14个不同浓度的Cr元素溶液中，浸泡时间为24小时，使马铃薯充分吸收Cr元素。待达到浸泡时间后将其取出，马铃薯表面的水分令其自然风干，待自然风干后用9#样品进行光谱采集，结果发现Cr元素的谱峰并不理想，出现这种结果的原因可能是由于样品中含水量的影响。因此对样品进行了干燥处理，样品的干燥程度根据样品质量进行估算，在样品干燥过程中隔一段时间取出使用天平进行称量，记录其质量，最终保持所有样品的质量依旧保持一致。

14 potato samples were immersed in 14 different concentrations of Cr element solution for 24 hours to allow the potatoes to fully absorb the Cr element. After the soaking time was reached, the potatoes were taken out and the surface water was allowed to air dry. The spectral collection was then performed using sample 9, but the Cr element peak was not ideal, which may be due to the influence of the water content in the sample. Therefore, the samples were dried, and the degree of drying was estimated based on the sample quality. During the drying process, the samples were taken out at intervals and weighed using a balance to record their weight, and the final weight of all samples was kept consistent.
