Effect of Anionic Polyacrylamide on the Structural Stability of Thickened Tailings Slurry in Pipeline Transportation - Hindawi
Taking the superfine tailings slurry (STS), fine tailings slurry (FTS), and unclassified tailings slurry (UTS) of a gold mine as examples, a series of laboratory shear tests were conducted to investigate the effect of anionic polyacrylamide (APA

Enhanced flotation selectivity of fine coal from kaolinite by anionic polyacrylamide pre-conditioning - ScienceDirect
The FTIR result of anionic polyacrylamide is showed in Fig. 3 (a).The absorption peak at 1117 cm −1, 1321 cm −1 and 1402 cm −1 was C N in the anionic polyacrylamide. The absorption peak at 1168 cm −1 and 1694 cm −1 refers to C C and C O in the a
Polyacrylamide (PAM) is a linear organic polymer, and it is the most widely used flocculant in water treatment chemicals.It can enhance flocculation, reduce the cost of clean water, improve water quality, and remove organic matter and algae in

A microblock structure type of anionic flocculant for hematite wastewater treatment: template copolymerization mechanism and enhanced flocculation
In this study, a novel anionic template polymer (TPAS) with microblock structure was prepared by ultraviolet light (UV)–assisted template copolymerization (UV-TP). Acrylamide (AM) and sodium styrene sulfonate (SSS) were selected as monomers and
Water treatment residuals produced after addition of polyaluminium chloride and anionic polyacrylamide (PAC-APAM WTRs) were evaluated for the potential to remove Cd2+ and Zn2+ from aqueous solutions by batch adsorption studies. The maximum
- Why is polyacrylamide used in water treatment?
- With the increasing global water scarcity and escalating environmental pollution, efficient water treatment has become paramount. Polyacrylamide, as a versatile polymer compound, has demonstrated significant achievements in the field of water treatment. PAM is widely used as a coagulant and flocculant in wastewater treatment.
- What are acrylamide and polyacrylamide used for?
- Acrylamide and polyacrylamide (PAM) are used in diverse industrial processes, mainly the production of plastics, dyes, and paper, in the treatment of drinking water, wastewater, and sewage. Besides inorganic form, acrylamide is formed naturally in certain starchy foods that were heated to cook a temperature above 120 °C for elongated time.
- 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.
- What is water soluble anionic polyacrylamide (PAM)?
- Water soluble anionic polyacrylamide (PAM) was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1–10 g m −3 in furrow irrigation water. Water flowing from PAM treated irrigation furrows show large reductions in sediment, nutrients and pesticides.
