    摘要: Methods of treating water to promote the health of aquatic organisms are described. The method may include introducing pulverized kaolin into the water. The pulverized kaolin may have a particle size distribution such that at least 30% by weight of the particles pass through a 60 mesh screen. For example, the pulverized kaolin may be in the form of a dry powder having a d50 diameter less than 300 µm. The pulverized kaolin may remain dispersed or suspended in the water without dispersants and/or surfactants, e.g., to reduce the amount of at least one pathogenic microorganism present in the water and/or to reduce or prevent exposure of aquatic organisms to the pathogenic microorganism(s).

    摘要: This invention is about silica monolithic particles, chromatographic stationary phases comprising them, and their manufacturing methods. The manufacturing process of silica monolithic particles of this invention includes three steps: the step for formation of bulk monolith (step 1) through sequential heating at three different temperatures, the step for powdering the silica monolith (step 2), and the step for calcination of the powdered silica monolith at 400-800 o C (step 3). In this invention, the manufacturing process for silica monolith particles becomes much simpler by removing the sieving and washing steps in comparison with the previous methods, causing great reduction of production cost. In addition, silica monolith particles with reduced average particle size and increased average pore size are obtained in this invention. Thus the stationary phases comprising the silica monolith particles of this invention result in high separation performance in liquid chromatography.
