Hi,
I am trying to plot different Cr species over x-y diagram. I would loke to plot pH on the x-axis and Total Chromium concentration on the y-axis. From the analysis, I have Cr (Total)= 14 mg/l, Cr+++= 8.5 mg/l, and Cr++++++= 5.5 mg/l and pH= 7.2. Could you please help me in plotting these data?
Thanks,
Ari
