2.3 Adsorption experiment
The adsorption experiments of CR and MB solutions by HP-HKUST-1/PES
membrane and HP-HKUST-1 powder is carried out by batch and continuous
adsorption, as shown in Figure 2 . HKUST-1/PES membrane and
HP-HKUST-1/PES membrane are used as adsorbents and fixed in the membrane
module. In the batch adsorption, the adsorption liquid is stirred by a
magnetic stirrer with constant speed. In continuous adsorption, the
entire unit is connected by a flexible pipe to form a circulating
system. The pre-prepared dye solution is forced to be fed into the
membrane module fixed with membrane adsorber. The effective area of the
membrane in the membrane module is 0.00047 m2.
