The invention relates to a method for effectively degrading algal
toxin in water. The method comprises the following
processing steps: (1) adding MC(
Microcystin)-LR into an
alcohol-water mixed
solvent, oscillating to enable the MC-LR to be completely dissolved, adding
ammonium hexafluorotitanate,
boric acid and
ammonium hexafluorosilicate, reacting for 15-25 hours at the constant temperature of 35 DEG C, immersing a
quartz fiber filter band into substances generated through the reaction, taking out and airing the
quartz fiber filter band, calcining the
quartz fiber filter band at the temperature of 400 DEG C for 2-2.5 hours with the temperature increasing rate of 10 DEG C / min, cooling, and taking out the
quartz fiber filter band, so as to obtain the
quartz fiber filter band loaded with
titanium dioxide porous micro-spheres with the
molecular imprinting function; (2) sewing the prepared
quartz fiber filter band loaded with the
titanium dioxide porous micro-spheres with the
molecular imprinting function into a filter sleeve capable of sleeving an
ultraviolet lamp tube according to the profile of the
ultraviolet lamp tube; (3) inserting the
ultraviolet lamp tube capable of being immersed into water into the filter sleeve, and then, placing the filter sleeve into a photoreaction container filled with
microcystin polluted water. Through the adoption of the method, the efficiency for degrading algal
toxin in water is relatively high.
