Preparation method of a floatable particle
The invention discloses a preparation method of a floatable particle. The method comprises the following steps: adding a water solution containing sodium alginate, an auxiliary agent or ethyl cellulose into a calcium chloride water solution, and carrying out crosslinking solidification at a certain temperature to obtain particles capable of floating on the surface of seawater or a seawater oil layer. The invention relates to a preparation method of the floatable particle. According to the preparation method, the concentration of sodium alginate is 1-3 wt%, the mass ratio of the auxiliary agentto sodium alginate is 1: 10-1: 100, the mass ratio of sodium alginate to ethyl cellulose is 1: 0.3-1: 6, the concentration of the calcium chloride water solution is 0.10-0.35 mol.L<-1>, the reactiontemperature is 25-80 DEG C, and the reaction time is 3-10 minutes. The preparation method provided by the invention is beneficial for the growth of flora, the increase of concentration and the effective contact between the flora and oil drops, and has the characteristics of simple and rapid preparation, low cost, easiness in amplification and field preparation, no secondary pollution and the like.
