The thermal decomposition of polyacrylamide (PAA) has received continued attention in the literature [1–5] for the following reasons: (i) PAA is used as an important thermoplastic material in many industries; (ii) the acrylamide monomer, which
Optimization of the conditions for degradation of hydrolyzed polyacrylamide using electro-coagulation
polyacrylamide (HPAM), which is difficult to treat using conventional biological methods because of its high molecular weight and viscosity. Electrochemical methods are considered to be effective for the treatment of refractory wastewater. In

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using
Transfer and degradation of polyacrylamide-based flocculants in hydrosystems: a review
This review focuses on the mechanisms of transfer and degradation, which can affect both PAM and residual AMD, with a special attention given to the potential release of AMD during PAM degradation. Due to the ability of PAM to adsorb onto

polyacrylamide : definition of polyacrylamide and synonyms of polyacrylamide (English)
In dilute aqueous solution, such as is commonly used for Enhanced Oil Recovery applications, polyacrylamide polymers are susceptible to chemical, thermal, and mechanical degradation. Chemical degradation occurs when the labile amine moiety

Purpose The applications of biochar (BC) and polyacrylamide (PAM) may have interactive effects on carbon (C) dynamics and sequestration for improving the soil quality and achieving sustainable agriculture. Relative to BC and PAM, rhizodeposits
- Can aluminium hydroxide polyhydrate be used as a filter for aqueous liquids?
- The present study developed a new secondary membrane, aluminium hydroxide polyhydrate, as a filter for aqueous liquids with potentially wide implications. To our knowledge, aluminium hydroxide hydrate gels that form from precipitates during their synthesis in water, although a well-known material, had not previously been used as separation devices.
- Why is aluminium hydroxide hydrate filtration important?
- Aluminium hydroxide hydrate filtration has potentially broad significance for safe water supply and human health. Its low cost and adaptability to various shapes makes it attractive for developing countries and for assisting existing technology for a range of water treatment and purification applications.
- What are filter presses used for?
- Among other uses, filter presses are utilised in marble factories in order to separate water from mud in order to reuse the water during the marble cutting process. Generally, the slurry that will be separated is injected into the centre of the press and each chamber of the press is filled.
- Can aluminium hydroxide hydrate gels be used for water filtration?
- Use of aluminium hydroxide hydrate gels for water filtration and comparison to conventional MF. The values show examples of various hydrate gel filters (normal or denser material at different strengths) under various pressures with either demineralized water or highly contaminated river water.
