Co-transport of Cu2+, Pb2+, Cd2+, and Zn2+ in the columns of

In the past few years, there is a notable trend that more and more municipal drinking water treatment plants have adopted the use of polyaluminium chloride (PAC) as a coagulant in water purification and anionic polyacrylamide (APAM) as the dewatering agent in the handling process of the sludge. This is true around the world, and especially in

Competitive adsorption of Cu2+, Pb2+, Cd2+, and Zn2+ onto water

Competitive adsorption of copper (II), lead (II), cadmium (II), and zinc (II) onto polyaluminium chloride and anionic polyacrylamide water treatment residuals (PAC-APAM WTRs) was evaluated with different pH, temperature, initial concentration, and time. The competitive adsorption removal increased with the increase of pH and temperature.

rheological properties of phpa polymer support fluids

Rheological Properties of PHPA Polymer Support Fluids

High-molecular-weight PHPAs are by far the most popular type of polymer used in foundation drilling (O¡¯Neill and Reese 1999), so the CETCO product was chosen as a representative of the class of products used in practice. The results of this work also should be of relevance to projects using other types of PHPA but with similar properties.

Insight into the Synergic Effect of Partially Hydrolyzed

The proposed addition of PHPA with the aim of avoiding or delaying the syneresis was successful at temperatures below 75 ¡ãC. Below the PHPA concentration of about 0.37 g/L, the effect of calcium chloride on syneresis was lower than polymer, whereas its effect overcame at the higher concentration.

Polyaluminium Chloride and Anionic Polyacrylamide Water

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 adsorption capacity obtained from Langmuir modeling was 85.5 mg Cd2+/g PAC-APAM WTRs or 25.6 mg Zn2+/g PAC-APAM WTRs. A Dubinin-Radushkevich (D-R) model

Recent progress in polymer hydrogel bioadhesives

Moreover, the research group developed a moisture-responsive and biocompatible smart hydrogel adhesive with an array of nano or microstructures on the surface in the dry state, which exhibited an adhesive strength up to 191 kPa. 41 Once in contact with water, the hydrogel adhesive underwent nano/micro and macro shape reconstruction, which shut down the adhesive (¡Ö0.30 kPa) with an extremely

Adsorptive removal of Pb2+ and Cu2+ from stormwater by using water

ABSTRACT The removal of heavy metal ions from stormwater runoff is a global issue. One of the critical solutions is the selection of innovative adsorbent used in stormwater bioretention systems. The potential use of water treatment residuals (WTRs) containing polyaluminium chloride and anionic polyacrylamide to remove divalent lead ions (Pb2+) and divalent copper ions (Cu2+) from stormwater
