Activated carbons and low cost adsorbents for remediation of tri- and hexavalent chromium from water.
Dinesh Mohan,Charles U. Pittman +1 more
TL;DR: The sorption capacities of commercial developed carbons and other low cost sorbents for chromium remediation are provided, and particular attention is paid to comparing the sorption efficiency and capacities of commercially available activated carbons to otherLow cost alternatives.

Adsorption of phenol and its derivatives from water using synthetic resins and low-cost natural adsorbents: a review
Su-Hsia Lin,Ruey-Shin Juang +1 more
TL;DR: The technical feasibility of the use of activated carbon, synthetic resins, and various low-cost natural adsorbents for the removal of phenol and its derivatives from contaminated water has been reviewed and it should be noted that the adsorption capacities of the adsorbent vary significantly depending on the characteristics of the individual adsorbENT, the extent of chemical modifications, and the concentrations of solutes.
Journal ArticleDOI
Soil structure as an indicator of soil functions: A review
TL;DR: In this paper, the potential of observable soil structural attributes to be used in the assessment of soil functions is evaluated and discussed from a methodological point of view and with respect to their relevance to soil functions.

Sol-gel based materials for biomedical applications
Gareth J Owens,Rajendra K. Singh,Farzad Foroutan,Mustafa Alqaysi,Cheol-Min Han,Chinmaya Mahapatra,Hae-Won Kim,Jonathan C. Knowles,Jonathan C. Knowles +8 more
TL;DR: A more detailed description of the biomedical areas where sol-gel materials have been explored and found to hold significant potential is given in this paper, where a generalized description of various solgel methods available and how these chemistries control the bulk properties of the end products is presented.
Journal ArticleDOI
Influence of pyrolysis temperature on characteristics and heavy metal adsorptive performance of biochar derived from municipal sewage sludge.
TL;DR: In the batch experiments of cadmium(II) adsorption, the removal capacity of biochars improved under higher temperature, especially at 800°C and 900°C even one order of magnitude higher than that of the commercial activated carbon.

TL;DR: The term rideal or rideal-Eley mechanism has been used for analogous processes in which there is a reactant molecule and a product molecule of nearly the same energy in the fluid phase or in some weakly adsorbed state and one or more atoms are never bonded to the surface.
