The adsorbance result of concentration, calculating is shown in Fig. 4.The result shows that with the increase of initial concentration, adsorbance also increases.In initial concentration
When for 100mg/L, activation montmorillonite biology carbon composite reaches 126mg/g to the adsorbance maximum of estradiol and ethinyloestradiol.
Embodiment 4
A kind of method that chemical activation/micro-wave digestion activation biological carbon materials remove fortimicin in water removal, step and reality
The Adsorption for applying fortimicin in 1 water body of example is identical, is different only in that: the pH value that solution is adjusted in embodiment 4 is 2.0-
10.0。
Concentration is the estrogen solution of 50mg/L after taking 25mL to dilute, and with concentration be 1M NaOH and HCl solution adjusts solution
PH value be 2.0,3.0,4.0,5.0,6.0,7.0,8.0,9.0 and 10.0 chemical activation/micro- made from 10mg embodiments 1 to be added
Wave resolution activation biological carbon materials, are placed in 25 DEG C of constant temperature oscillations, water-bath constant temperature oscillator revolving speed is 180rpm, and duration of oscillation is
For 24 hours, after reaction, solution sedimentation, using 0.45 μm of Teflon filtration (syringe type).It is anti-with ultraviolet specrophotometer measurement
The concentration of fortimicin in rear solution is answered, the adsorbance result of calculating is shown in Fig. 5.The result shows that pH is 4.0 or so, activation is covered de-
Stone biology carbon composite reaches maximum to the adsorbance of estrogen.
