Lab Study on the Effect of Cation Exchange Capacity
The shale of the lower Cambrian Niutitang formation in northwestern Hunan is an ideal reservoir for shale gas. There is a close connection between borehole stability and drilling fluid in shale
Polymers made from natural biomass are gaining interest due to the rising environmental concerns and depletion of petrochemical resources. Lignin isolated from lignocellulosic biomass is the second most abundant natural polymer next to cellulose. The paper pulp process produces industrial lignin as a byproduct that is mostly used for energy and has less significant utility in materials

- Does polyacrylamide increase teff yield?
- Overall, this study demonstrated that the use of polyacrylamide (PAM) with biochar on slightly acidic, and with lime on moderately to strongly acidic soils increased teff yield with highest net benefit and marginal rate of return than application of PAM, gypsum, lime, biochar, and farmyard manure alone or PAM + gypsum treatments and the control.
- Does anionic polyacrylamide reduce soil erosion?
- Anionic polyacrylamide (PAM) has the potential to reduce soil erosion through soil conditioning. However, a comprehensive study about its effectiveness especially when applied combined with other amendments have rarely been conducted in the tropical highland climatic conditions, such as in Ethiopia.
- What is polyacrylamide used for?
- ... Polyacrylamides and their water soluble-derived copolymers became lately the most widely used materials in many fields, such ascorrosion inhibition and water treatment by coagulation/flocculation [1, 2] as they offer the possibility to be charged.
- What is hydrolyzed polyacrylamide containing wastewater treatment?
