  • Le lithopone a été découvert dans les années 1870 par DuPont. Il a été produit par la Krebs Pigments and Chemical Company, entre autres1. Il se faisait en différents grades, en fonction de la teneur en sulfure de zinc. Les qualités « bronze » et « or » contenaient 40 à 50 % de sulfure de zinc, ce qui les rendaient particulièrement couvrantes2. Bien que ce pigment ait atteint son pic de popularité autour de 1920, il s'en produisait encore annuellement plus de 220 000 tonnes en 1990. Il est principalement utilisé dans les peintures, les pâtes et les plastiques3.

  • Finally, gravimetric analysis is a traditional method for determining barium in TiO2. This technique involves weighing the precipitate formed by reacting the sample with a reagent and then calculating the mass of barium present. Gravimetric analysis offers high accuracy and precision, but it is time-consuming and labor-intensive.

  • The additive goes into a lot of personal care products to whiten and brighten colors and to make them opaque, like toothpaste and makeup.

  • 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.
