Coupling heat curing and surface modification for the fabrication of high permselectivity polyamide nanofiltration membranes

Surface modification is an efficient post-treatment method to optimize the properties of nanofiltration (NF) membranes. Here, we report a facile surface modification strategy coupling with heat curing for grafting monoethanolamine (MEA), a monomer containing both a primary amine and a primary alcohol group, onto a nascent polyamide NF membrane. With grafting 0.5 wt% MEA at 50 degrees C, the pure water permeability of the polyamide NF membranes was improved from 7.9 to 19.5 L m(-2) h(-1) bar(-1) due to their enhanced physicochemical property, such as superior hydrophilicity, rough surface morphology, and enlarged membrane pores. Meanwhile, the rejection of Na2SO4 remained above 97.5%. More importantly, the optimal membrane modified with 0.5 wt% MEA exhibited a high Na2SO4 rejection of 99.1% and a negative NaCl rejection of -20.1% when treating a mixed salt solution containing 2 g/L Na2SO4 and 2 g/L NaCl. Our study provides a novel insight for the fabrication of high permselectivity NF membranes via surface modification.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3391-86-4, in my other articles.

Joint Effect of Alcohol Drinking and Environmental Cadmium Exposure on Hypertension in Korean Adults: Analysis of Data from the Korea National Health and Nutrition Examination Survey, 2008 to 2013

Background Hypertension is a common disease found in 1.13 billion adults worldwide. Several animal studies have provided evidence of the joint effect of alcohol drinking and cadmium exposure on hypertension. However, no epidemiologic study has examined the association between these 2 risk factors and hypertension. Therefore, we examined the individual effects of alcohol drinking and cadmium and the joint effect of their coexposure on hypertension in the general population. Methods We analyzed data from 8,403 South Korean adults who had been randomly assigned to the Korea National Health and Nutrition Examination Survey from 2008 to 2013. Multiple linear and logistic regression analyses were conducted to estimate the association of alcohol drinking and blood cadmium concentration with blood pressure and the odds ratio (OR) for hypertension. Results The weighted prevalence of hypertension and high-risk drinking was 25.7 and 13.6%, respectively. The weighted geometric mean of blood cadmium levels was 0.94 mu g/L (95% confidence interval [CI]: 0.93 to 0.96). After adjusting for demographic characteristics, anthropometric measurements, health-related behaviors, and dietary and disease variables, the OR for hypertension in the group with the high-risk alcohol drinking was 1.67 (95% CI: 1.34 to 2.06) compared with the group without high-risk alcohol drinking. When the highest and the lowest blood cadmium quartiles were compared, the OR for hypertension was 1.46 (95% CI: 1.15 to 1.86). The positive joint effect of high-risk drinking and blood cadmium levels was statistically significant for systolic blood pressure (SBP; p = 0.037) and diastolic blood pressure (DBP; p < 0.001). Conclusions Our results show that heavy alcohol drinking had a joint effect with cadmium exposure to increase the risk of hypertension. Future efforts are needed to reduce alcohol drinking and environmental cadmium exposure to prevent hypertension in the general population. Interested yet?
