Preparation: Instruments: Prepare a 721 spectrophotometer (or other spectrophotometers that meet the requirements), an electronic balance, a stoppered conical flask, a magnetic stirrer, a thermometer, a volumetric flask, etc.   Reagents: Polyacrylamide (HPAM) powder, determine its molecular we...

Choosing the right type of polyacrylamide is crucial for various applications such as wastewater treatment, enhanced oil recovery, papermaking, and mining. With a wide range of polyacrylamide types available, selecting the most appropriate one requires careful consideration of several factors. Here...

Polyacrylamide, a water-soluble polymer, can improve oil recovery efficiency through a process known as enhanced oil recovery (EOR). There are several mechanisms by which polyacrylamide achieves this:     1. Viscosity Modification: Polyacrylamide can increase the viscosity of the water in...

Polyacrylamide (PAM) is a synthetic polymer that is primarily used for its flocculation, coagulation, and viscosity-enhancing properties. The role of polyacrylamide polymer varies depending on the application, but some of its main functions include:   1. Flocculation and Coagulation: Polyacryla...

Polyacrylamide (PAM) is a widely used polymer with various applications across different industries. Some of the key application areas of polyacrylamide include:   1. Water Treatment: Polyacrylamide is extensively used in water treatment processes such as flocculation and sedimentation. It aids...

Cationic polyacrylamide (CPAM) is a type of polymeric flocculant that is commonly used in sludge dewatering processes. Sludge dewatering involves the removal of water from sludge to reduce its volume and facilitate its disposal or further treatment. CPAM is used as a conditioning agent to improve th...

The molecular structure formula of polyacrylamide can be represented as: Conh2[CH2-CH]N This formula represents the repeating unit in the polymer chain of polyacrylamide. Each unit consists of an acrylamide monomer (CH₂=CHCONH₂) in which the amide group (-CONH-) connects the monomers together to for...
