Anionic polyacrylamide influence on the lead(II) ion accumulation in soil – the study on montmorillonite
Purpose Polymeric substances, as soil conditioners, limit the erosion process as well as improve the soil structure. The same macromolecular compounds may influence the heavy metal accumulation in soil environment. The main aim of this study was

Hence, under environmentally relevant conditions, anionic polycarboxylates generally show strong sorption to activated sludge, soil particles, and other solids [18, 58, 62]. A K d of 1,825 L/kg was determined for sorption of P-AA (16.1 kDa) to
Improving soil properties, especially in arid and semiarid regions, is an urgent need for sustainable food production. This study aims to evaluate the effect of applying two types of anionic polyacrylamide polymers (PAMs) with different
POLYACRYLAMIDE SOIL AMENDMENT EFFECTS ON RUNOFF AND SEDIMENT YIELD ON STEEP SLOPES: PART I SIMULATED RAINFALL CONDITIONS
Transactions of the ASAE Vol. 45(5): 1327–1337 2002 American Society of Agricultural Engineers ISSN 0001–2351 1327 POLYACRYLAMIDE SOIL AMENDMENT EFFECTS ON RUNOFF AND SEDIMENT YIELD ON STEEP SLOPES: PART I. SIMULATED RAINFALL CONDITIONS
Production capacity expansion by the companies is shaping the polyacrylamide market. Manufacturers in the polyacrylamide industry are scaling up their production capacities and expanding their production capabilities to meet increased demand
Agriculture | Free Full-Text | Coal Fly Ash and Polyacrylamide Influence Transport and Redistribution of Soil Nitrogen in a Sandy Sloping Land | HTML
Sandy soils are prone to nutrient losses, and consequently do not have as much as agricultural productivity as other soils. In this study, coal fly ash (CFA) and anionic polyacrylamide (PAM) granules were used as a sandy soil amendment. The two
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for
Using polyacrylamide to control erosion on agricultural and disturbed soils in rainfed areas
Zhang and Miller (1996) studied the effect of anionic polyacrylamide on soil erosion in Using polyacrylamide to control erosion on agricultural and disturbed soils in rainfed areas D.C. Flanagan, L.D. Norton, J.R. Peterson, and K. Chaudhari
Owing to its significant capacity to conserve water in soils, polyacrylamide (PAM) hydrogels have been applied extensively in croplands to combat droughts. However, the influences of different mechanical and chemical factors of sand on its
- What are cationic polyacrylamide copolymers?
- Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).
- Can cationic polyacrylamide be used in oilfield wastewater treatment?
- Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
- Are cationic polyacrylamide copolymers harmful to the environment?
- Environ Sci Eur. 2018; 30 (1): 16. Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.
- What type of polyacrylamide is used in oil industry?
- The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
