The first group
was associated with NOS and COS at 450 C and 650 C, respectively,
where the maximum sorption capacity was almost within
the same range (25.25e32.36 mg/g), whereas in the second group,
therewas a significant, increasing trend of Cd biosorption by COS at
750 C, 800 C, and 900 C, with the maximum sorption capacity reaching values of 344.83 mg/g, 833.33 mg/g, and 1666.67 mg/g,
respectively (Table 4).
