  • Vapor Suppressing Sorbent

    SDI PetroZorb is a granular sorbent that makes sorbed flammable liquids non-hazardous by suppression of the vapor pressure. At typically recommended levels of application, standard ASTM closed cup flash point measurements indicate that the sorbed liquid has flash points above the flammable hazard limit of 1400 F for a range of fuels and industrial and ...

  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Removal of contaminants from industrial wastewater through various non-conventional technologies: a review

    It is difficult to separate industrial growth from environmental pollution but it can be minimised through cost-effective approaches of pollution abatement. To reach the full objectives of zero pollution, adoption of alternative technologies which suit the situation of low capital availability, minimum man-power and limited energy consumption are necessary. Adsorption through agricultural ...

  • Retention of 2,4,6-trinitrotoluene and heavy metals from industrial waste water by using the low cost adsorbent pine bark in a batch experiment

    Pine bark is a low cost sorbent originating from the forest industry. In recent years, it has been found to show promise as an adsorbent for metals and organic substances in contaminated water, especially landfill leachates and storm water. This study aims to investigate if pine bark can replace commercial adsorbents such as active carbon. An industrial effluent, collected from a treatment plant ...

  • Sampling of Carbonyls Using a Dual-Layer LpDNPH Glass Sampling Tube and HPLC Analysis

    The dual-layer LpDNPH sorbent tube is an air sampling device designed for sampling carbonyls (e.g. formaldehyde) in ambient, indoor, and industrial atmospheres. Carbonyls are trapped on our high-purity silica gel adsorbent coated with 2,4-dinitrophenylhydrazine (2,4-DNPH) where they are converted to stable hydrazone derivatives. The derivatives are eluted from the tube in acetonitrile and ...

  • Sorption of thallium(I) ions by peat

    The increasing industrial use of thallium has raised the need for removal of this highly toxic element from wastewater. Thallium is more toxic than cadmium, copper, zinc, lead and mercury and as it is easily accumulated in humans, animals and plants, it poses a threat to both the environment and human health. Peat has been used as an effective, relatively cheap and easily available sorbent to ...

  • Comparative performance of cement kiln dust and activated carbon in removal of cadmium from aqueous solutions

    This study compared the performance of cement kiln dust (CKD) as industrial byproduct and commercially activated carbon (AC) as adsorbent derived from agricultural waste for the removal of cadmium (Cd2+) from aqueous solutions. CKD and AC were characterized by Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) and surface areas demonstrate the differences of ...

  • Study of equilibrium and kinetic models for removal of chromium (VI) and lead (II) by modified feather by H 2 O 2

    Heavy metals are sorely toxic for the environment and human. In this study, the ability of feather for sorption chromium and lead from aqueous solution was investigated. All the experiments were carried out in a batch system. For this aim, the effect of various parameters such as pH, temperature, contact time, dosage sorbent and initial concentration were investigated. Results showed that ...
