Silica gel desiccant
Name: Silicone Alias: Silica gel oxide or silicic acid gel Molecular formula: xSiO2-yH2O Molecular weight：60.08 CAS Registry Number：CAS# 112926-00-8 EINECS Registry Number: 231-545-4 Explanation of words Chemical formula xSiO2-yH2O. transparent or milky white granular solid. It has open porous structure and strong adsorption ability, and can adsorb many kinds of substances. When dilute sulfuric acid (or hydrochloric acid) is added to the aqueous solution of water glass and left to stand, it becomes a water-silicate gel and solidifies. The electrolyte Na+ and SO4 2-(Cl-) ions dissolved in it are removed by water washing, and silica gel is obtained after drying. If absorbing water, some silica gel moisture absorption is about 40%, even 300%. It is used for gas drying, gas absorption, liquid dehydration, color layer analysis, etc. It is also used as a catalyst. If cobalt chloride is added, it will be blue when dried and red after absorbing water. It can be regenerated and used repeatedly.

Differences Between Anionic, Cationic, and Non-Ionic Polyacrylamides
Anionic Polyacrylamide (APAM) features a negative charge and high molecular weight, offering solutions for wastewater with cationic pollutants and aiding in mining and pulp industries. Cationic Polyacrylamide (CPAM), with a positive charge, addresses anionic pollutants and is pivotal in municipal and industrial wastewater, papermaking, violin quality improvement, and efficiency augmentation in the petroleum sector. Lastly, Non-Ionic Polyacrylamide (NPAM), being neutral, effectively treats wastewater under neutral to weakly acidic conditions, showing useful applications in textiles, paper industries, and the petroleum sector. The selection of a flocculant is critical and relies on the charge type of pollutants, operational conditions, and economic viability in various treatment sectors.
