Which reagent is best among 'Dimethylglyoxime" and "Dithiothreitol" for spectroscopic determination of Nickel ?

What I think is Dithiothreitol. As it is water-soluble and does not form a precipitate. But, the thing is it contains sulphur which is quite hazardous to aquatic animals.

The plant classification keys " Taxonomic Key " are used to classify and identify plants

The imagej program is used to measure the leaf area and not to classify it

Also, the shape of the leaf can be recognized by looking and does not need mathematical programs and methods

For any shape the centroid-radii model can be used to get a vector representation : find the centroid and draw multiple radii from it to the periphery, calculate normalized lengths of the radii and store in a vector. Other than that statistical measurements like major axis, minor axis, perimeter, area etc. can provide shape representations.
