Rapid, Selective Heavy Metal Removal from Water by a Metal-Organic Framework/Polydopamine Composite

Wendy Lee Queen, Emad Oveisi, Seyedmohamad Moosavi, Daniel Teav Sun, Li Peng, Davide Tiana

Drinking water contamination with heavy metals, particularly lead, is a persistent problem worldwide with grave public health consequences. Existing purification methods often cannot address this problem quickly and economically. Here we report a cheap, wa ...

Characterizing the Effects of a “Switchable Water” Additive on the Aqueous Solubility of Small Molecules

Paul Joseph Dyson, Philip Gregory Jessop, Sarika Burra

“Switchable water” is an aqueous solution containing a water‐soluble amine additive that exhibits CO2‐switchable properties, such as large changes in ionic strength, by forming an ammonium bicarbonate salt. Switchable water has been used to reversibly “sal ...

Young runoff fractions control streamwater age and solute concentration dynamics

Andrea Rinaldo, Paolo Benettin, Gianluca Botter

We introduce a new representation of coupled solute and water age dynamics at the catchment scale, which shows how the contributions of young runoff waters can be directly referenced to observed water quality patterns. The methodology stems from recent tre ...

Thermal water purification system and method for operating said system

Chin Lee Ong

The present invention relates to a thermal water purification system (10) for producing a distillate liquid from a raw liquid (LP, LB) comprising: - a plurality of distilling units (1 a-1h) which are consecutively flowed through by the raw feed liquid (LP, ...

Decomposing the Bulk Electrical Conductivity of Streamflow To Recover Individual Solute Concentrations at High Frequency

Paolo Benettin

The ability to evaluate stream hydrochemistry is often constrained by the capacity to sample streamwater at an adequate frequency. While technology is no longer a limiting factor, costs and sample management can still be a barrier to high-resolution water ...

Point-of-use water filters can effectively remove disinfection by-products and toxicity from chlorinated and chloraminated tap water

Urs von Gunten

Epidemiological risk estimates point toward potential health risks posed by disinfection by-products ( DBPs) in chlorinated drinking water. Point-of-use filters can effectively remove regulated DBPs from tap water but the removal of unknown DBPs and toxici ...

A mild biomass pretreatment using gamma-valerolactone for concentrated sugar production

Jeremy Luterbacher, Ydna Marie Questell-Santiago, Li Shuai

Here we report that gamma-valerolactone (GVL), a biomass-derived solvent, can be used to facilitate the mild pretreatment of lignocellulosic biomass. An 80% GVL, 20% water solvent system was used to pretreat hardwood at the mild temperature of 120 degrees ...

Emerging investigators series: prediction of trace organic contaminant abatement with UV/H2O2: development and validation of semi-empirical models for municipal wastewater effluents

Urs von Gunten, Minju Lee, Yun Ho Lee

Recent evaluations of potable reuse treatment trains suggest that the use of UV and UV/H2O2 may become increasingly common, particularly in systems employing ozone and/or biofiltration. This study provides a summary of photolysis rate constants and (OH)-O- ...

Biomass-burning impact on CCN number, hygroscopicity and cloud formation during summertime in the eastern Mediterranean

Athanasios Nenes

This study investigates the concentration, cloud condensation nuclei (CCN) activity and hygroscopic properties of particles influenced by biomass burning in the eastern Mediterranean and their impacts on cloud droplet formation. Air masses sampled were sub ...

Levels of 48 pesticides in vegetables and water and evaluation of health risk resulting from dietary intake in gardening areas in Burkina Faso

Luiz Felippe De Alencastro, Edouard René Gilbert Lehmann

Exceedance of MRLs might induce a risk for the consumers and limits the opportunities of exportation for a sector identified by the authorities as having a great potential for the fight against poverty. In the same way, levels of some water samples exceed ...
