In this work, nanomesopose SBA-16 was prepared from reed plant stem by green method and used to remove Phenolphthalein pollutant. The effect of different parameters (pH, initial concentration of phenolphthalein, amount of SBA-16 adsorbent, temperature and contact time) on the amount of phenolphthalein absorption by the prepared adsorbent was investigated with the help of experiment design software. The results of the predicted experiments showed that the highest absorption of phenolphthalein was in the conditions of pH=4.01, temperature 44°C, contact time 20 min, initial concentration of adsorbent 13 mg/L and amount of adsorbent 0.05 g. can be seen. In optimal conditions, the prediction of the software was 100% removal of phenolphthalein from the water environment, which actually achieved a removal of 99.46%. Considering the high potential of nanomesopore SBA-16 in removing phenolphthalein pigment, it can be considered as a suitable candidate for removing colored pollutants and treating wastewater from textile factories.
