(3) extract the silk gum throw out;
(4) the silk gum throw out is carried out purifying and drying, obtain silk gum.
In the above-mentioned recovery method that is dissolved in the silk gum in the come unglued liquid, said recovery method can also comprise the steps:
(1) come unglued liquid is carried out filter just;
(2) first filter back come unglued liquid is carried out purifying;
(3) come unglued liquid behind the purifying is carried out electrolysis, obtain the silk gum throw out;
(4) the silk gum throw out is carried out drying, obtain silk gum.
Just the process of filter is in order to remove tangible impurity in the come unglued liquid.The process of purifying is to realize desalination through means such as dialysis.
Preferably, in the above-mentioned recovery method that is dissolved in the silk gum in the come unglued liquid, the electrode materials that adopts in the electrolysis is graphite or titanium.
Preferably, in the above-mentioned recovery method that is dissolved in the silk gum in the come unglued liquid, the voltage that applies in the electrolysis step is 20～50V.Preferred, the voltage that applies is 25V～30V.
Correspondingly, the invention also discloses a kind of silk gum, especially, said silk gum is to obtain according to above-mentioned recovery method.
