can-1333	Li, Duo; Xu, Nan	Sedimentation of nanoparticle titanium dioxide in the presence of ammonium	2021	7	.pdf	application/pdf	3047	149	50	In view of this, the authors mainly studied the mechanism of NH4+ on nTiO2 particle settlement, studied the settlement curve of pH values, calculated the settlement rate through Zeta potential and nanop- ularity, and then explained the influence and mecha- nism of NH4+ on the settlement rate of nTiO2 particles in water bodies. Dilute 1000 mg·L–1 titanium standard solu- tion to 1–5 mg·L–1 for measurement, and obtain the standard curve of nTiO2 concentration (as shown in Figure 1).	cache/can-1333.pdf	txt/can-1333.txt
