heavy metals are considered one of the most important environmental pollution and are dissolved form or adsorbed to the suspended solides in the urban storm runoffs and infiltratire ponds. in this article the heavy metals of urban storm runoff and sediments of infiltration pond in shiraz city have been investigated. the results show different pollutions in the urban storm runoffs such as dissol...

The management of agricultural waste is an important issue related to environment protection, as the inappropriate disposal this yields negative effects on environment. Proper industrial effluents totally aligned with sustainable development goal (SDG) number six “clean water and sanitation”, well partially other several SDG. In work, two materials were used for vanillic acid recovery from wast...

Langmuir and Freundlich isotherm adsorption models were used to predict iron lead removal from automobile workshop stormwater runoff. Combined low-cost filter systems consisting of granular activated carbon–rice husk (GAC–RH) river gravel–granular carbon (GR–GAC) in this study. The effects adsorbent dosage contact time on the capacity adsorbents, as well efficiencies systems, also investigated....

In 2015, more than 30% of erasers were found to contain a PAE content that exceeded the 0.1% limit established by the Quality and Technology Supervision Bureau of Jiangsu Province in China. Thus, strengthening the supervision and regulation of the PAE content in foods and supplies, in particular, remains necessary. Graphene oxide (GO) and its composites have drawn great interests as promising a...

Abstract To contribute to the reduction of methane emissions, using low-cost biochar as adsorbents for capturing and storing in oil gas fields is investigated. This work presents results adsorption on four biochars made from forestry wastes comparison with three commercial activated carbons. Although capacity lower by over 50% than that carbons, thelow-cost potential environmental benefits prov...

As an extracorporeal technique for blood purification, haemoadsorption was introduced in the early 1960s along with other physico-chemical methods. The problem of poor biocompatibility of uncoated adsorbents was resolved by coating adsorbent granules with haemocompatible membranes. Use of coated adsorbents instead of uncoated ones reduces the efficiency of haemoperfusion. As a result, for many ...

the adsorption ability of miswak (salvadora persica l.) waste was investigated for the removalof common heavy metals; pb(ii), cu(ii), ni(ii) and cd(ii), from aqueous systems. the miswak mainlyconsists of saponins, tannins, silica and resin, which are accounted for the removal of heavy metal ions fromaqueous systems. the effects of various parameters, such as solution ph, contact time, initial c...

Nowadays environmental pollution is a great threat to us. Water resources are mostly polluted by industrial wastes. Among all other pollutions, water one of the most vital caused different sources like industrial, domestic, sewage, hazardous waste, municipal medical manufacturing etc. Public concern over impact wastewater has increased. There several methods for treatment wastewater. them, tech...

Fluoride is one of the anionic contaminants which is found in excess in surface or groundwater because of geochemical reactions or anthropogenic activities such as the disposal of industrial wastewaters. Among various methods used for defluoridation of water such as coagulation, precipitation, membrane processes, electrolytic treatment, ion-exchange, the adsorption process is widely used. It of...

Aflatoxins (AF) are a class of mycotoxins that impair poultry health and performance by causing immune suppression, liver damage, and changes in serum chemistry. The toxic effects of AF can be efficiently counteracted by some adsorbents. The aim of this study was to investigate fully characterized clay adsorbents in a feeding trial with broiler chickens to correlate in vitro and in vivo AF deto...
