As simple method for the rapid analysis of radiostrontium in drinking water, river water and seawater

Radiostrontium (mainly strontium-90, 90Sr) belongs to the radionuclides, which are emitted to the environment when nuclear fission gets out of control. The main source is from bomb fallout. Radiostrontium was released to the environment from 1945…1970, when

Bioelectro-Fenton: a sustainable process for the removal of pharmaceuticals residues from water

Water scarcity is one of the main environmental issues humanity is facing. This situation is aggravated by the constant release of refractory contaminants into water reservoirs due to the incessant growth of the industrial activity. These so

Electromembrane extraction and spectrophotometric determination of As(V) in water samples

Arsenic is an important environmental element because of its high toxicity at the level of parts per billion. According to World Health Organization (WHO) guideline on drinking water quality, the maximum permitted concentration of arsenic in drinking

Active ingredients in personal care products detected throughout the environment

On a daily basis, we use a variety of personal care products, including soaps, detergents, sunscreens, fragrances, insect repellents, cosmetics, and shampoos.  In fact, the US Bureau of Labor Statistics estimates that the average household spends over

Flocculation/sterilization dual-function starch-based water treatment agents

Recently, multi-function water treatment agents have attracted much attention. Traditional water treatment agents usually possess single functionality, resulting in production of a wide variety of agents at high doses, complicated devices, and fussy operations in practical applications.

What is coagulation/flocculation and chitosan-based flocculants used in water treatment?

Insoluble suspended colloids are frequently the main contaminants in raw water which make water look very dirty. Moreover, those colloidal particles are usually small and also surface charged, thus the electrostatic repulsion effects among them cause the

New account of wetting phenomena at the nanoscale

Can you think of any very smooth surface in nature or in the man-made objects surrounding you? How about a glass window? Glass is smooth, right? very smooth? Well in reality standard glass substrates, and any other

A benevolent anionic ZnII-MOF to purify water and make medicines

Metal-organic frameworks (MOF) are well-known crystalline porous materials comprising metal ions or metal clusters bridged by different types of organic linkers. MOFs have been in the spotlight globally owing to their tunable surface area, functionalizable pore surface,

Can solar driven processes effectively control antibiotic resistance and cytotoxicity during drinking water treatment?

Antibiotics, antibiotic resistant bacteria and antibiotic resistant genes have been detected in various aquatic environments because of the disposal of both treated and untreated wastewater. Their occurrence in water is a threat for human and animal health

Lithium ion intercalation for boosting photoelectrochemical water splitting performance of TiO2 photoelectrode

Energy shortage and environmental pollution inspire the exploration of clean, renewable, and non-fossil energy carriers. Hydrogen, as “the world’s cleanest energy” because of its raw materials and products are water, and high energy content per unit mass

Contamination of newly built thermal plants – does water hold the answer?

A domestic central heating system uses a boiler, powered by electric or gas, to heat water. This is then pumped around the system to radiators that heat a room by radiation and convection. The heat transfer fluid

Ionic liquid solubilities in water: a janus phenomenon

Ionic liquids are a new class of solvents often claimed as « green » because they are non-flammable and non-volatile. In the search for better environmental industrial processes, they are thus an appealing choice to replace toxic, flammable and

Selective naked-eye sensors for real time detection of mercury ion in water

Mercury (Hg) is one of the most harmful and toxic chemical pollutants, which is released into the environment through natural or industrial sources. This dangerous heavy metal has the ability to enter the food chain and accumulate

Climate-friendly wastewater management

A major part of the energy loss from new energy-efficient buildings is the emission of warm wastewater to the sewers. This leads to increased interest for heat recovery from domestic wastewater, which may contain up to 800

Grow TiO2 nano-crystals on cellulose to sequester lead in water

Heavy metals in water pose significant threat to environment and public health. Lead, for example, when present above the action level in drinking water as a toxin, can cause a variety of adverse health effects such as

Probing how alcohol affects the structure of water

Water, despite its ubiquity, is an extraordinarily complex substance. The structure of water on a molecular level is defined by the interactions, “hydrogen bonds”, that individual molecules have with each other. These are the reason that upon
