Ammonia | NH3 - PubChem
Ammonia is a colorless gas with a very distinct odor. This odor is familiar to many people because ammonia is used in smelling salts, many household and industrial cleaners, and window-cleaning products. Ammonia gas can be dissolved in water. This kind of ammonia is called liquid ammonia or aqueous ammonia.

Results showed that the removal efficiencies of COD, TSS, NH3-N and PO4 3- were 93, 98, 80 and 30% respectively. On average 91% of influent soluble microbial products (SMP) were eliminated, with the eliminations of polysaccharides mostly above 80%.
A Cation Study on Rice Husk Biomass Pretreatment with
Biomass pretreatment is a key first step in converting recalcitrant lignocellulosic biomass into value-added products. Aqueous hydroxide solutions can be effective biomass pretreatment media, and the cation of the hydroxide salt can have an extremely significant effect upon the physicochemical behavior of the hydroxide solution. However, the cation effect has not been comprehensively

Effective environmental management of any poultry waste begins with an understanding of its composition and the physical, chemical, and microbiological reactions that control the fate of potential pollutants in the waste following land application.
Trifluoroacetic acid | CF3COOH - PubChem
Trifluoroacetic acid was not biodegraded during a year-long study using laboratory aquatic microcosms and ecosystem sediment-water systems. A pKa of 0.52 indicates trifluoroacetic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate

- What is a high molecular weight polyacrylamide (PAM)?
- ... High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- Can polyacrylamide improve hydrocarbon production efficiency?
- npj Materials Sustainability 2, Article number: 15 (2025) Cite this article Polyacrylamide (PAM) and its derivatives play a pivotal role in various facets of hydrocarbon development. Proper application and treatment of PAM have the potential to enhance hydrocarbon production efficiency while mitigating adverse environmental effects.
- Can polyacrylamide contribute to residual polymer formation?
- Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.
- What is polyacrylamide (PAM) used for?
- npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
