剂会释放一部分没食子酸,而达到新的平衡.此外,抑藻剂投加于水体之后,会浮于水面,释放时间足够其较均匀的分布,不会造成局部浓度过高. 图1 壳聚糖载没食子酸抑藻剂的用量对解吸的影响 Fig. 1 Effect of dosage of CTS-GA on desorption 2.3 壳聚糖,没食子酸和抑藻剂对水华微囊藻生长的影响 壳聚糖对水华微囊藻的影响如图2......
at higher immersion period indicates desorption of the inhibitor molecules from the metal surface. The results obtained in Table 2 clearly indicate that, the RC increases and the η decreases......
resistance change was defined as the response time in the case of adsorption and the recovery time in the case of desorption. 3 Results and discussion 3.1 Structure and morphology of ZnO nanosheets... morphology mainly formed by absorbing RuO2 nano particles onto the ZnO nanosheets. Ru content of 2.41% in the RZS was confirmed by EDS (see Fig. 3(d)). The curves of N2 adsorption-desorption isotherm......
