The work aims to study a catalyst with adsorption and degradation for more efficient purification of ink wastewater. Through redox precipitation method, the natural clinoptilolite was modified by MnOx, and the natural clinop-tilolite and MnOx modified clinoptilolite were studied to purify the ink wastewater. The crystal form, pore structure and morphology of MnOx modified clinoptilolite were investigated. The effects of treatment time and treatment temperature on COD and chroma removal rate of ink wastewater were systematically studied. The results showed that, the MnOx modified clinoptilolite maintained the crystal structure and morphology of clinoptilolite, and had higher specific surface area, pore volume and wider pore size distribution. Under the optimal treatment conditions, the MnOx modified clinoptilolite has higher removal performance than the natural clinoptilolite. The COD and chroma removal rates of ink wastewater can reach over 98% and 99% at 20 ℃ for 15 min.
