Synthesis of a high adsorption capacity material for pollutions removal is temping research and practical field due to increasing the environmental pollution in industrial communities. In this study, a new covalent organic framework based on triazine rings was synthesized and characterized by FTIR spectra, Xray di raction pattern, elemental analysis, and nitrogen adsorptiondesorption isotherm. Because of the nitrogen riched surface, mesoporous structure, and large surface area, the synthesized Nriched triazinebased COF had a super adsorption capacity. The adsorption properties were examined with the removal of DFS4BS from textile wastewater. The effective parameter on adsorption performance and color removal processes such as pH, contact time, temperature, and adsorbent dosage were optimized with Central Composition Design. The optimum condition was pH 2 Temperature: 35 C Absorbent dosage: 0.01 g and contact time: 360 min. The obtained maximum adsorption capacity was 8501 mg g 1 (850 wt %) that indicates the super adsorption ability of synthesized Nriched TCOF. To reduce the colorimetric test price and develop the presented adsorbent for field applicability, a mobile phone colorimeter was constructed with accessible equipment and investigate the accuracy of that by comparing the data of mobile phones with the obtained result from UVvis spectrometer.
