                         Voltammetry (SWASV) measurements by using boron doped diamond 
                         electrodes with different morphologies from micro to 
                         nanocrocrystalline grains as Boron Doped Diamond (BDD) and Boron 
                         Doped Nanocrystalline Diamond (BDND), respectively. The argon 
                         concentrations, in the argon/hydrogen ratio, used were 0, 50, 60, 
                         70, and 80 vol.%. SWASV technique was applied in 4  10\− 4 
                         mol L\− 1 ammonium acetate buffer pH 4.2. The peak currents 
                         were measured for Cd2 + concentration ranging from 1 to 20 
                         \μg L\− 1. This change in film grain size and 
                         roughness affected how cadmium was deposited on the electrode 
                         surfaces, thus affecting its electroanalytical response from SWASV 
                         measurements as well as its selectivity. For all electrodes 
                         cadmium detection limits (DL) were lower than 1 \μg 
                         L\− 1 while for BDND electrode DL reached 0.016 \μg 
                         L\− 1. These values are lower than that required by the 
                         Brazilian Health Ministry for potable water (1 \μg 
                         L\− 1) and confirm that diamond electrodes are a suitable 
                         mercury-free method to determine cadmium trace levels in water. A 
                         strong correlation between the electrode selectivity and its grain 
                         size also confirmed the best performance of BDND electrode.",
