WebBase on the pK a values, the speciation of ciprofloxacin can be calculated: at solution pH=5.6, ciprofloxacin showed 80% cationic and 20% zwitterion species; at pH=9.5, ciprofloxacin showed 83.4% anionic and 16.6% zwitterion. Surface charge of soil minerals is also determined by soil solution pH base on point of zero charge (PZC) of soil.
