将经过校准后的SX-620 笔式 pH 计浸润进待测的模拟废水中，待显

Immerse the calibrated SX-620 pen pH meter into the simulated wastewater to be tested, and read the reading after the displayed pH is stable. The active groups in the SG-APT-DDF adsorbent were analyzed by Fourier transform infrared spectroscopy. The surface microstructure of SG-APT-DDF was observed by scanning electron microscope FlexSEM1000. The molecular weight of the product flocculant was determined by viscometry.
