degradation of polyacrylamide and its significance in nature

acrylamide at a dose of 20 mg/kg/day stimulated the degeneration of peripheral nerves and the spinal cord of rats, although no obvious effects were found at doses less than 0.2 mg/kg/day. 152

(pdf) microbial degradation of polyacrylamide and the,the polyacrylamide and its degradation products by sec showed that the molecular weight of the polyacrylamide had reduced from 2000 to 500 kda during the e. agglomerans cultivation.

degradation of polyacrylamide and its significance in nature

polyacrylamide (hpam), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic pam in oil and gas development as well as in soil conditioning. 1 , the most

biodegradation of polyacrylamide and its derivatives manufacturer,although polyacrylamide (pam) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual pam are urgently needed. biodegradation of pam and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation. microorganisms have been shown

trends in polyacrylamide utilization and treatment for sale

pam plays increasingly important roles in the oil and gas industry. among a wide range of polymers, pam, and its derivatives are extensively employed in hf fluid (table 1).the usage of pam (5.6

polyacrylamide (pam) for sale water treatment chemical,nonionic polyacrylamide is a very effective flocculant and can be used for various types of sewage treatment. its characteristics are: its flocculation performance is less affected by the ph value of wastewater and salts, and the flocculation strength is higher than that of anionic flocculants, especially in the treatment of acidic wastewater, the effect is better than that of anionic pam.

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

best price cationic flocculants anionic flocculants.cationic flocculant,it is commonly used as a flocculant in the water treatment process in industries of mining, metallurgy, textile, papermaking and so on. It is also a multipurpose chemical used in oil industry. flocculant features： 1. the flocs are tight and the

highly efficient degradation of polyacrylamide by an fe-doped

polyacrylamide (pam) in environmental water has become a major problem in water pollution management due to its high molecular mass, corrosion resistance, high viscosity, and nonabsorption by soil. the composite of fe-doped ce0.75zr0.25o2 solid solution (fe-ce0.75zr0.25o2) loaded on carbon felt (cf) was fabricated by a hydrothermal synthesis method, which was used as the cathode in a

fabricating an anionic polyacrylamide (apam) with an anionic,2.3. characteristics of copolymers the intrinsic viscosities of polymers (η) used to assess the absorption and bridging ability was conducted on an ubbelohde viscosity meter (shanghai shenyi glass instrumental co. ltd., china) in a 2 mol l −1 aqueous nacl solution at 30 °c, 13 and the molecular weight of the polymer was calculated by huggins equation displayed in esi text s1.
