Abstract: The present disclosure relates to a method for recycling a taurine mother liquor, which includes: adding a base to the taurine mother liquor, heating to a first temperature, carrying out a hydrolysis reaction, removing ammonia produced, and evaporating and concentrating the ammonia-removed solution to obtain an alkali metal hydroxyethyl sulfonate solution. When applying the method provided by the present disclosure for the recycling of the taurine mother liquor, the taurine mother liquor can be further converted into the alkali metal hydroxyethyl sulfonate solution, impurities are removed from the obtained alkali metal hydroxyethyl sulfonate solution, the impurity-removed alkali metal hydroxyethyl sulfonate solution is concentrated and crystallized, and the alkali metal hydroxyethyl sulfonate is separated out. The method provided by the present disclosure is an efficient and simple method for recycling the taurine mother liquor, which is very easy to implement industrially and can effectively recycle the taurine mother liquor.

Abstract: Micro-nano materials, products obtained by covalently modifying the surfaces of micro/nano materials with hydrophilic materials, and methods for making the same. The micro/nano materials on the surfaces have carboxyl groups or/and pro-carboxyl groups which are converted into their active esters. The products are covalently modified by forming amide bonds between the active esters on the surfaces and the modification agents; where the modification agents are hydrophilic compounds and/or hydrophilic polymers bearing primary and/or secondary aliphatic amines. Monomers bearing carboxyl groups and/or pro-carboxyl groups are used to produce an adequate number of carboxyl groups and/or pro-carboxyl groups on the surface of a polymer material to be modified. The carboxyl groups and/or pro-carboxyl groups are converted into active esters. A reasonably-sized modification agent bearing primary and/or secondary amines, zwitterions and hydrophilic linear spacer arms is used to form amide bonds and obtain a covalently modified surface layer.
