We know that there are a lot of suspended organisms and colloidal impurities in natural water. The forms of suspended solids are different. Some large particles of suspended solids can settle under their own gravity. The other is colloidal particles, which is an important reason for the turbidity of water. Colloidal particles can not be removed by natural settlement, because colloidal particles in water are mainly clay with negative electricity The Brownian motion of colloidal particles and the hydration on the surface of colloidal particles make colloidal particles have dispersion stability. Among them, electrostatic repulsion has the greatest influence. If coagulant is added to water, it can provide a large number of positive ions and accelerate the coagulation and precipitation of colloid. Compressing the diffusion layer of micelles makes the potential change into an unstable factor, which is also conducive to the adsorption and condensation of micelles. The water molecules in the hydrated film have fixed contact with the colloidal particles and have high elastic viscosity. It is necessary to overcome the special resistance to expel these water molecules. This resistance hinders the direct contact of the colloidal particles. The existence of some hydrated films depends on the electric double layer state. If coagulant is added to reduce the zeta potential, the hydration may be weakened. The polymer materials formed after coagulant hydrolysis (the polymer materials directly added into water generally have chain structure) play an adsorption bridging role between the colloidal particles. Even if the zeta potential does not decrease or does not decrease much, the colloidal particles can not contact each other and can be adsorbed through the polymer chain Colloidal particles can also form flocs.

3) Metathesis reaction: Dissolve the sulfide in distilled water to obtain a clear decomposition liquid, and add nonionic surfactant to stir evenly, then slowly add it to the zinc sulfate ammonia complex solution to form a metathesis reaction, and obtain Lide powder opacity. The liquid is separated by filtration, and the separated ammonia liquid is returned to the leaching after ammonia adjustment, and the separated nZnS-BaS0 4 crystal filter cake is put into the next step;

Les pouvoirs couvrant et éclaircissant du lithopone normal sont supérieurs à ceux de la céruse et de l'oxyde de zinc, mais inférieurs au Dioxyde de Titane pur, étant le meilleur blanc sous tout rapport. C'est le sulfure de zinc qui, avec son indice de réfraction de 2,37, est l’élément opaque ; le 2nd composé, le sulfate de baryum, joue un rôle de diluant minéral et favorise l'efficacité de la diffusion du premier.

One of the most notable characteristics of mixed crystal nano titania is its ability to absorb light across a wide range of wavelengths. This property makes it an excellent photocatalyst, capable of driving chemical reactions using only sunlight as the energy source. As such, it has found use in environmental remediation efforts, where it can help break down pollutants and harmful chemicals in water and air. Additionally, its high surface area-to-volume ratio allows for efficient adsorption of gases and liquids, making it useful in sensors and filters.
