| titleOfInvention | Composite separation membrane and separation membrane element |
| abstract | The present invention provides a new composite separation membrane capable of improving the permeation flux and suppressing a decrease in the blocking rate of dissolved substances other than humic acid such as salts contained in a liquid to be separated. A composite separation membrane according to the present invention includes a porous support and a separation functional layer formed on the porous support. The separation functional layer is composed of a polyamide formed by a reaction of a compound group including an aliphatic polyfunctional amine, a linear hydrocarbon chain-containing polyfunctional amine, and a polyfunctional acid halide. An aliphatic polyfunctional amine has two or more secondary amino groups. The polyfunctional amine containing a linear hydrocarbon chain is a primary amino group bonded to the end of the linear hydrocarbon chain and a primary amino group or secondary bonded to the other end of the linear hydrocarbon chain. Has an amino group. The proportion of the linear hydrocarbon chain-containing polyfunctional amine in the polyfunctional amine in the compound group is less than 15 mol%. [Selection] Figure 1 |
