Hi!
I would like to enquire is there any method for determining the concentration of arsenic in water without using sofisticated instrument?
Colourimetric/ spectrophotometric method may be a option.
HACH makes a low and high range Arsenic test kit which is fairly inexpensive.
Low range kit (0-500 ppb As):
https://www.hach.com/arsenic-low-range-test-kit/product?id=7640217303&callback=qs
High range test kit (0-4000 ppb As):
https://www.hach.com/ez-arsenic-high-range-test-kit/product?id=7640217305&callback=qs
each kit allows for 100 test to be performed
An alternative method is to utilize a rapid colorimetric method for measuring arsenic. A good paper is by Dhar et al., 2004, A rapid colorimetric method for measuring arsenic concentrations in groundwater, Analytical chimica Acta, 526, pp 203-209.
