Hydrochloric Acid - The Definitive Guide | Biology Dictionary
Another hydrogen chloride use in industry is the production of inorganic compounds such as poly aluminum chloride (PAC), iron (III) chloride (iron trichloride) and aluminum chlorohydrate. The use of hydrogen chloride is necessary at the start of
A commercial PHPA known as ‘Shore Pac’ was used to prepare the test fluids. This polymer is supplied in dry granular form by CETCO Drilling Products. The molecular weight and the degree of hydrolysis have been determined as 20 × 10 6 g/mol and
Application progress of enhanced coagulation in water treatment - RSC Advances (RSC Publishing)
The main products are aluminum sulfate, ferrous sulfate, iron sulfate, polyaluminum chloride (PAC) and PFS. The hydrolyzed polymerization products of these products have a positive charge, and through the adsorption and neutralization sweeping

Review: optical fiber sensors for civil engineering applications
Optical fiber sensor (OFS) technologies have developed rapidly over the last few decades, and various types of OFS have found practical applications in the field of civil engineering. In this paper, which is resulting from the work of the RILEM
With ferric chloride as the principal coagulant, Table 7 shows that each of the PAC doses employed was sufficient to achieve complete cyanobacteria removal. Increasing the PAC dose between 5 and 20 mg/L gave lower filtered water turbidities, and

- Can nonionic polyacrylamide be used as a gel fracturing fluid?
- Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
- Why is nonionic polyacrylamide used as anti-scouring admixture?
- Nonionic polyacrylamide was selected as anti-scouring admixture to eliminate the influence of different polymer electrical properties (Lu et al. 2025 ). The molecular weight of PAM is more than 10 million Daltons, and its main chain is connected with a C=O bond and an amino functional group as a branch chain structure, as shown in Fig. 2.
- What is nonionic polyacrylamide?
- Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
- What is a high-molecular-weight nonionic polyacrylamide?
- High-molecular-weight nonionic polyacrylamides are routinely used in the mineral processing industries as thickeners and flocculants [36–38]. The product types for polyacrylamides are solutions, liquids (emulsion or dispersion), and dry powders. The forms each have their own set of advantages and disadvantages as will be discussed in the following.
