MOFs　are　usually　used　as　efficient　adsorbents　to　remove　specific　pollutants　in　water.　However,　because　of　their　poor　water　stability　relatively　small　particle　size,　their　application　in　adsorbing　and　removing　pollutants　from　water　is　limited.　In　this　paper,　with　nitrile　rubber　sponge　as　the　substrate,　UiO-66-NH2/sponge　composites　were　firstly　in　-situ　synthesized　and　systematically　evaluated　UiO-66-NH2　as　an　adsorbent　to　remove　2,4-dichlorophenoxyacetic　acid　from　water.　This　composite　could　not　only　remain　the　adsorption　capacity　for　2,4-dichlorophenoxyacetic　acid　of　UiO-66-NH2,　but　also　was　much　more　convenient　for　separation　after　the　adsorption　compared　to　UIO-66-NH2.　In　addition,　the　mechanism　of　the　adsorption　of　UiO-66-NH2　for　2,4-dichlorophenoxyacetic　acid　were　discussed　in　detail.　Electrostatic　interaction　between　UIO-66-NH2　and　2,4-dichlorophenoxyacetic　acid　was　the　main　adsorption　mechanism.　The　adsorption　was　mainly　suitable　for　Langmuir　isotherm　models,　and　its　maximum　adsorption　capacity　of　2,4-dichlorophenoxyacetic　acid　was　72.99　mg　g(-1).
