degradation of polyacrylamide and its significance in nature
high quality flocculant polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction enhancer.
the effect of anionicity on mechanical degradation of sale,non-ionic and anionic polyacrylamide (pam)-based flocculant chains are commonly employed in a vast majority of tailings treatment operations and several studies have been conducted on degradation of pam due to various factors such as ph, light and temperature, microbial degradation [11] and chemical degradation [12]. the effects of
evaluation an anionic polyacrylamide flocculant with low cost
in this study, a template polymer with anionic microblock structure was successfully synthesized through ultrasonic initiated template copolymerization (ustp) by using sodium allylsulfonate (sas) and acrylamide as monomers, poly diallyl dimethyl ammonium chloride (polydadmac) as template, and 2,2′-azobis [2-(2-imidazolin-2-yl) propane] dihydrochloride (va-044) as initiator.
polymer based flocculants review of water purification,polyacrylamide (pam) is the basis for most commercial polymeric flocculants mentioned in the literature (anionic, cationic, or non-ionic); this polymer is also modifiable with combinations of comonomers. anionic pam; the most important category of pam, can be made by copolymerizing acrylamide with acrylic aid or partially hydrolysing
transfer and degradation of polyacrylamide-based flocculants
the aim of this review was to summarize information and scientific data from the literature dedicated to the fate of polyacrylamide (pam)-based flocculants in hydrosystems. flocculants, usually composed of pam, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. these polymers can contain
cationic polyacrylamide copolymers (pam): environmental half,background cationic polyacrylamide copolymers (pam) 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 pam in soils. to obtain detailed information on the polymer’s fate in the soil compartment, the degradation of 14c
recent achievements in polymer bio-based flocculants for sale
among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (pam)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process. the acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
