As can be seen from Table 2, the modified fibre of preparation of the embodiment of the present invention is organic to ammonia, acetic acid, the isovaleric acid in water
Small molecule has good absorption property, under glass fibre-bamboo charcoal fiber good adsorption properties, bentonite, silicon powder, coconut palm charcoal
Powder can play good absorption synergistic effect.It is living due to lacking bentonite and coconut husk respectively in comparative example 1, comparative example 2
Property charcoal, so that the interlayer structure of the blended bamboo charcoal fiber of glass fibre lacks caking property, adsorptivity, small organic molecule cannot be introduced into layer
Between structure be adsorbed, reduce the adsorptivity to small organic molecule.
Adsorption of metal ions performance test
Modified fibre 10g prepared by Example, comparative example, is added 48h in the metal ion waste water of 600mL, passes through electricity
Feel coupled plasma optical emission spectrometer and tests adsorption of metal ions amount.Wherein, in metal ion waste water, the concentration of iron ion is
1000ppm, the concentration of copper ion are 800ppm, and the concentration of lead ion is 500ppm, and the concentration of mercury ion is 260ppm.It is specific to survey
Test result is shown in Table 3.
3. adsorption of metal ions the performance test results of table
As can be seen from Table 3, the modified fibre of the embodiment of the present invention is more to iron ion, copper ion, lead ion, mercury ion etc.
Metal ion species have excellent absorption property.Due to lacking bentonite and cocoanut active charcoal respectively in comparative example 1, comparative example 2,
So that the interlayer structure of the blended bamboo charcoal fiber of glass fibre lacks caking property, adsorptivity, metal ion cannot be introduced into interlayer structure
It is adsorbed, reduces the adsorptivity to metal ion.
