If you do an absorbance reading after plasmid purification and get a A260/A280 of less than 1.8, how could you further purify the sample to get rid of the protein contamination

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
