The amount of aluminum in seawater varies between approximately 0.013 and 5 ppb. The Atlantic Ocean is known to contain more aluminum than the Pacific Ocean. River water generally contains about 400 ppb of aluminum. Aluminum mainly occurs as Al
Polybutylene – Chemical Engineering Materials of Construction
Polybutylene. Polybutylene (PB) is a material f construction also known as Polybutene-1 (PB-1) and it is a member of the polyolefin family of thermoplastics. Polybutylene is produced by polymerizing butene-1 using Zeigler-Natta catalysts which
chloride, bromide and cyanide ions by reacting with silver ions to form a brick-red silver chromate precipitate in the equivalence point region. The Mohr method uses chromate ions as an indicator in the titration of chloride ions with a silver

- 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.
- What is nonionic polyacrylamide (NPAM) gel?
- Nonionic polyacrylamide (NPAM) gel was prepared for in-depth profile control. A compact three dimensional network structure was formed in the bulk gel system. Retention, adsorption and bridging across the pore throats occur in high permeability zones. The NPAM gel shows superior high temperature resistant. °C.
- How to control NPAM molecular weight?
- The NPAM molecular weight can be controlled by adjusting these factors. The decisive factor is the acrylamide concentration, whereas the initiator concentration and feeding temperature are secondary factors. These synthetic NPAMs can be crosslinked with zirconium acetate to produce a gel fracturing fluid for use in low permeability oil reservoirs.
- What factors affect NPAM molecular weight?
- The effects of the monomer concentration, initiator concentration, reaction time, feeding temperature and reaction temperature on the molecular weight were systematically investigated through single-factor and orthogonal experiments. The NPAM molecular weight can be controlled by adjusting these factors.
