11. Obtained ZnTPP-H250HT has a absorption band at 423 nm in ethanol suspension, corresponding to Soret band of ZnTPP. However, the intensity of Soret band in the absorption spectrum of ZnTPP-H250HT is noticablly decreased compared to that of ZnTPP. The color changed from red-purple to bluish green. Peak intensities of both the absorption and fluorescence emission spectra linearly increased with an increase in the concentration of ZnTPP-H250HT ethanol suspension in the range of 0.1 to 0.4 wt%, and error was within 10%.

13. The time required to complete the reaction varied depending on the amount of adsorbent and concentration of p-chlorophenol. In the case of run 3, the peak at 224 nm was not recognized after 1.5 h, however, it took more than 45 h for complete disappearance of the peak in the condition of run 6.
