Quantitation of acrylamide (and polyacrylamide
An empirical model was constructed in terms of related significant design parameters to describe the polyacrylamide conversion (%) as the response. Based on the response surface plots and analysis
Based on the response surface plots and analysis of variance (ANOVA), optimum redox polymerization obtained was: 1.0335M acrylamide, 5x10-4 M ammonium persulphate and 1x10-4 M sodium bisulfite

the response surface plots and analysis of variance (ANOVA), optimum redox polymerization obtained was: 1.0335M acrylamide, 5x10 -4 M ammonium persulphate and 1x10 -4 M sodium bisulfite under 65 o C, producing 96.89% of polyacrylamide in 10 minutes.
A statistical design kinetics model was constructed through second-order regression to predict the rate of polyacrylamide redox polymerization and the R-2 value was 0.9888, which fitted the

Polyacrylamide (PAM)-grafted multi-walled carbon nanotubes (MWCNTs-g-PAM) which are dispersable in water were prepared by the surface initiated redox polymerization of acrylamide using ceric
Redox Polymer - an overview | ScienceDirect Topics
Redox polymers are also known by the names oxidation-reduction polymers, electron-transfer polymers or electron-exchange polymers [33]. Reversible redox reaction can take place in a polymer main-chain, as in the case of PANI and quinone/hydroquinone polymers, or in side-groups, as in the case of a polymer-carrying ferrocene side-group [3].
The redox responsiveness of these PFS films allows for controlled and repeatable switching of the surface energy of the PFS-I and PFS-SO3– layers under electrochemical control. Static water/surface contact angle measurements showed a change in contact angle values for PFS-I from 80° (reduced state) to 70° (oxidized state) over repeated cycles.

Quantifying the effect of polyacrylamide dosage, Na+
In this study, we used a response surface methodology to systematically assess the impact of Na + and Ca 2+ concentration and anionic polyacrylamide dosage in the flocculation and dewatering of MFT. We observed a beneficial synergistic effect between Ca 2+ concentration and polyacrylamide dosage, although excess of Ca 2+ may reduce

Response Surface Methodology Response surface methodology is a statistical method frequently used in designing experimental, building models, for evaluating the effects of several factors and to find the optimum conditions for desirable responses as well as to reduce the number of experiments [11,12].

- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
- What is poly aluminum chloride used for?
- Contact us! Poly aluminum chloride is used mainly to remove color and colloidal matter in aqueous systems. It is also used in water treatment plants, clarification of industrial effluents and as a replacement for aluminum sulfate, aluminum chloride, ferric chloride, ferric sulfate and other non-polymerized conventional inorganic salts.
- How long does it take to deliver poly aluminum chloride?
- Theses salts works as clarifiers in the following water treatment processes: to the MEX-USA border, our deliveries take 2 to 3 weeks. Contact us! Poly aluminum chloride is used mainly to remove color and colloidal matter in aqueous systems.
- Does high-purity PACL reduce operating cost?
- On the other hand, when the dose was greater than 4 mg L −1 as Al, the high-purity PACl showed great UV 254 -absorbance removal capacity; which was even much greater at high does (e.g., 10 mg L −1). Relative low dose requirement of high-purity PACl indicates the potential of the reduction of operating cost.
