The present invention relates to a bipolar membrane for a water-decomposing electrodialysis process, and more particularly, to a method for producing a bipolar membrane by bonding a sulfonated cation exchange membrane and an aminated anion exchange membrane, and a method for producing a bipolar membrane, Cell.

전기에너지를 이용하면 물속의 전해질을 농축하거나 반대로 제거할 수 있다. 이 공정에서 이온이 선택적으로 투과하는 막이 필요하게 된다. 또한 전기장 아래에서 이온교환막을 이용하는 공정은 전기투석(ED, electrodialysis)이라고 부른다.Electrical energy can be used to concentrate or reverse the electrolyte in the water. In this process, a film selectively permeable to ions is required. Also, the process of using an ion exchange membrane under the electric field is called electrodialysis (ED).

초기에는 전기투석 공정의 경제적 효율성을 높이기 위해 전기저항이 낮은 막을 제조하는 것이 연구의 주된 목표였지만 최근에는 물분해를 일으키는 바이폴라막, 일가 이온만을 선택적으로 투과시킬 수 있는 막, 막오염을 줄일 수 있는 막 등과 같이 특수한 성질을 갖는 이온교환막을 제조하기 위한 연구가 활발히 진행되고 있다. Initially, to improve the economic efficiency of the electrodialysis process, it was the main objective of the research to produce a membrane with low electrical resistance. However, in recent years, the bipolar membrane causing water decomposition, the membrane selectively permeable to monovalent ions, Studies have been actively conducted to produce ion exchange membranes having specific properties such as membranes.

물분해 전기투석(WSED, Water-Splitting ElectroDialysis) 공정은 물을 수소이온(H+)과 수산화이온(OH-)으로 분해시킬 수 있는 바이폴라막을 전기투석에 도입한 것으로서, 기존의 사용되던 전해 공정에 비해 에너지 소모량이 낮고 대용량화가 용이하다는 장점을 가지고 있다. 또한 WSED공정은 환경오염 저감 및 자원회수에 적합한 기술로서, 이는 철강산업의 산세폐액 처리회수를 비롯해 펄프제지산업 등 다양한 화공생물산업 분야에서 응용되고 있다. The water-splitting electrodialysis (WSED) process is the introduction of a bipolar membrane capable of decomposing water into hydrogen ions (H +) and hydroxide ions (OH-) into electrodialysis, It has the advantage of low energy consumption and high capacity.

Therefore, it is necessary to study a bipolar membrane and a stack cell for a water-decomposing electrodialysis process that does not require such a large-capacity tank.

상기 제조예 1에서 제조한 양이온교환막 (5종)과 제조예 에서 제조한 음이온교환막 (3종)을 접합하여 바이폴라막을 제막하였으며, 상기 제조예 1 및 제조예 2에서 제조한 이온교환막 소재의 조합을 달리하여 총 18종을 제조하였다. 이때 음이온교환막과 양이온교환막의 비율은 1:1, 2:1, 3:1 비율이 되도록 바이폴라막을 형성하였다.The bipolar membrane was formed by bonding the cation exchange membranes (5 kinds) prepared in Preparation Example 1 and the anion exchange membranes (3 kinds) prepared in Production Example, and the combination of the ion exchange membrane materials prepared in Production Example 1 and Production Example 2 A total of 18 species were produced. At this time, the bipolar membrane was formed so that the ratio of anion exchange membrane to cation exchange membrane was 1: 1, 2: 1, 3: 1.

또한, 바이폴라막의 전기저항 값을 감소시키기 위해 양이온교환막을 FeCl3 수용액으로 농도를 달리하여 (2 wt%, 5 wt%, 10wt% 등) 촉매처리하고 음이온교환막과 결합시켜 양이온교환막과 음이온교환막 사이에 촉매층이 형성된 바이폴라막도 제조하여 그 효과를 비교하고자 하였다.In order to reduce the electrical resistance of the bipolar membrane, the cation exchange membrane was catalytically treated with FeCl 3 aqueous solution at different concentrations (2 wt%, 5 wt%, 10 wt%, etc.) and bonded to the anion exchange membrane A bipolar membrane with a catalyst layer was also fabricated and its effect was compared.

물분해 전기투석(WSED) 실험을 하기 위해 제작된 셀에 바이폴라막 1장, 양이온교환막 2장, 음이온교환막 1장을 각각 순차적으로 넣고, 이온교환막 사이에 유로를 형성한 후 산용액과 염기용액이 순환적으로 흐르도록 하였다. 셀 내부 이온교환막은 양이온교환막, 바이폴라막(음이온면, 양이온면 순), 음이온교환막, 양이온교환막 순서로 조립하였으며, 양이온교환막과 바이폴라막 사이로는 염기성 용액(NaOH 등)이 흐르고, 바이폴라막과 음이온교환막 사이로는 산성용액(HCl 등)이 그리고 음이온교환막과 양이온교환막 사이로는 염용액(NaCl 등)이 흐르도록 구성하였다.
In order to conduct the water-decomposing electrodialysis (WSED) experiment, one bipolar membrane, two cation exchange membranes and one anion exchange membrane were sequentially placed in the cell, and a channel was formed between the ion exchange membranes, So as to flow cyclically. The ion exchange membrane inside the cell was assembled in the order of cation exchange membrane, bipolar membrane (anion side, cation side order), anion exchange membrane and cation exchange membrane. Basic solution (NaOH, etc.) flows between cation exchange membrane and bipolar membrane, and bipolar membrane and anion exchange membrane (NaCl, etc.) flows between the anion exchange membrane and the cation exchange membrane.

본 발명의 실시예에서 산용액으로는 염산(HCl), 염기용액으로는 수산화나트륨(NaOH), 염용액으로는 염화나트륨(NaCl), 전극수로는 수산화나트륨(NaOH)를 사용하였으며, 셀에 정전류를 흘려 주고 일정유량을 흘려 보내 주었다.In the examples of the present invention, hydrochloric acid (HCl) was used as an acid solution, sodium hydroxide (NaOH) was used as a base solution, sodium chloride (NaCl) was used as a salt solution and sodium hydroxide (NaOH) I flowed and flowed a certain amount of flow.

WSED실험 결과는 하기 표 2 내지 표 37에 산과 염기의 농축량(생성량) (단위: g/L)과 전압 값 (단위: V) 으로 나타내었으며, 6시간까지의 실험값을 정리하였다. 하기 결과 값은 바이폴라막에 있어서 양이온교환막과 음이온교환막의 비율이 1 : 2인 경우를 대표적으로 나타내었으며, 비율이 1 : 1과 1 : 3로 달라지는 경우 1 : 2를 기준으로 산/염기의 생산량이 조금씩 감소 또는 증가하는 경향을 보였고, 전압 값에는 큰 차이가 없었다.The results of the WSED test are shown in Tables 2 to 37 below in terms of concentration (amount) (unit: g / L) of acid and base and voltage value (unit: V). The following results are typical for the case where the ratio of cation exchange membrane to anion exchange membrane in the bipolar membrane is 1: 2. When the ratio is 1: 1 and 1: 3, the acid / base production Showed a tendency to decrease or increase slightly, and there was no significant difference in voltage value.

본 발명의 실험시간은 최소 4시간에서 최대 12시간까지 진행하였으며, 하기 표 2 내지 표 37에서 알 수 있는 바와 같이 대부분의 구간에서 일정하게 산과 염기의 생산량이 증가했다. 또한 양이온교환막과 음이온교환막 사이에 촉매층을 형성시킨 경우, 전압 값은 더 낮고 안정적으로 유지되었으며, 산과 염기 생산량은 더 증가하는 경향을 보였다.Experimental time of the present invention ranged from at least 4 hours to at most 12 hours. As can be seen from Tables 2 to 37, production of acid and base was constantly increased in most of the sections. Also, when the catalyst layer was formed between the cation exchange membrane and the anion exchange membrane, the voltage value was kept lower and stable, and the acid and base production tended to increase further.
