The article provides an overview of the literature on the role of sorption detoxification using intestinal adsorbents (enterosorption method) in the multifaceted treatment of various diseases. The mechanism of action of adsorbents and their therapeutic effects are presented. We emphasized that intestinal adsorbent Enterosgel is a modern, effective, and safe detoxifying agent.

Nanocrystalline zinc oxides are produced by chemical vapor synthesis and characterized by x-ray diffraction, high resolution transmission electron microscopy, nitrogen sorption, and extended x-ray absorption fine structure. Dopant elements aluminum, gallium, and indium influence the particle size of the powders as well as lattice parameters and local structure. The different effects of the thre...

The aim of this study is to prepare biogenic sulphides by using bacteria for the removal of zinc cations from their solutions. The production was realized in a bioreactor under anaerobic conditions at 30 °C. Sorbents were prepared by sulphate-reducing bacteria in different nutrient medium modifications, under two modes of bacteria cultivation. Created precipitates of iron sulphides were removed...

Many metal-organic frameworks are water labile, including the iconic Hong-Kong University of Science and Technology-1 (HKUST-1). Spray-dry encapsulation of HKUST-1 crystals into polystyrene microspheres is reported here to yield composites that are resistant to water but retain most of the excellent gas sorption capacity of HKUST-1. These composites are demonstrated to exhibit superior water ad...

zinc (zn) availability and mobility in soils is controlled by its interaction with the soil matrix and amendments. contradicting evidence has been reported for factors influencing zn behavior in soils. the aim of this study was to investigate the zn sorption in selected acid, calcareous and gypsiferous soils with different background electrolytes (na+, k+ and h2po4, no3 and cl backgrounds). iso...

Previous studies demonstrated the environmental and economic benefits of treating lead(II)-contaminated water streams with ferrihydrite in multiple equilibrium sorption stages. In this work, multistage ferrihydrite sorption systems were evaluated for their effectiveness in reducing single-solute zinc(II) (Zn(II)) concentrations in contaminated water streams to very low levels. As for lead(II) (...

A permeable reactive barrier, consisting of a mixture of compost and calcite gravel, was built in Aznalcóllar (SW Spain) to treat acidic groundwater containing zinc, aluminium and copper. Monitoring results show that practically no dissolved sulphate is reduced as water flows through the barrier, which has a residence time of about 1 to 2 days. Despite this lack of bacterial activity significan...

Temperature and relative humidity (RH) are two major external factors, which affect equilibrium moisture content (EMC) of wood-plastic composites (WPCs). In this study, the effect of different durability treatments on sorption and desorption isotherms of southern yellow pine (SYP)-high density polyethylene (HDPE) composites was investigated. All samples were equilibriumed at 20 °C and various R...

Highway runoff from IP 4, a mountain road in the north-east of Portugal, has been monitored using a system integrating a raingauge, a flowmeter and an automatic water sampler. Average daily traffic (ADT) is 6000 and the study catchment has 5970 m2 of total area and 2500 m2 of road pavement. A single stormwater outlet discharges into an infiltration pond with overflow to a creek. Sampling was ca...
