Table 3

Comparison of results obtained by proposed procedure and the reference method.

Sample	Hypochlorite (mg L^−1)
	Proposed	DPD [31]
A	0.471 ± 0.008	0.462 ± 0.005
B	0.026 ± 0.001	0.026 ± 0.001
C	0.026 ± 0.00	0.027 ± 0.001
D	0.471 ± 0.004	0.428 ± 0.005
E	0.274 ± 0.006	0.270 ± 0.005
F	0.027 ± 0.001	0.026 ± 0.000

Results are average of the four consecutive sample analyses. No significant difference at 95% confidence level, 𝑡_tabled=2.447, 𝑡_calculated=1.360.
