In this method, the diffusion current is proportional to the concentration of the substance, and a change in the concentration to be determined is immediately reflected in the value of diffusion current [4-6].
The diffusion current is proportional to concentration of MTB with plateau potential at -1.
The temperature coefficient values of diffusion current as shown in Table 1 and 2 are found to be between 1.
1] is the diffusion current ([mu]A) at lower temperature and [i.
These criteria are based on the polarographic diffusion current [i.
A plot of the proportional growth in the diffusion current of the first wave versus HQ concentration yields n-apparent values listed in Table 1.
In all the cases decrease in diffusion current
occurred with increasing ligand concentration.
This removes the need to evaluate ionic currents and diffusion currents
at millions of sites, and allows the use of a much lower spatial resolution (in the order of 1 mm).
