Adsorption equilibrium and kinetics on lignocellulosic base adsorbents from oil palm bagasse (OPB) yam peels (YP) were studied for the removal of hexavalent chromium present in aqueous solution, a batch system, evaluating effect temperature, adsorbent dose particle size process. Isotherms fitted to Langmuir, Freundlich Dubinin–Radushkevich isothermal models. Kinetic data adjusted pseudo-first-o...

The role of enzyme engineering in biotechnology, biological and pharmaceutical process cannot be over emphasized. This study compared the adsorption of digestives enzymes; amylase, protease and lipase on to Zn-ferrite (ZnFe2O4). The metal ferrite was synthesized via a sol-gel technique and characterized with scanning electron microscopy (SEM), X-ray diffraction (XRD), Electron paramagnetic reso...

Activated carbon prepared from coir pith (ZnCPC) using ZnCl2 was investigated to find the feasibility of its application for removal of 2,4–dichlorophenol (2,4-DCP) in aqueous solution through adsorption process. Batch mode kinetics and isotherm studies were carried out to evaluate the effects of contact time, initial concentration, adsorbent dose, pH, and temperature. Lagergren, Second order, ...

An adsorbent prepared by entrapping active carbon derived from the stems of Achyranthes aspera plant in the calcium alginate beads (CABAA) has been investigated for its adsorption nature towards the removal of phosphate by varying various physicochemical parameters. Surface morphological studies are made using FTIR, XRD, FESEM, and EDX. The sorption mechanism is analyzed using Freundlich, Langm...

Two species of the genus Baruscapillaria Moravec, 1982 are known to parasitise the small intestine of the common cormorant, Phalacrocorax carbo (L.): Baruscapillaria carbonis (Dubinin et Dubinina, 1940) and B. rudolphii Moravec, Scholz et Nasincová, 1994. A redescription of the former species, based on specimens collected from common cormorants shot in South Bohemia, Czech Republic, is provided...

The aim of this paper is to investigate the removal of toluene from gaseous solution through Glycyrrhiza glabra root (GGR) as a waste material. The batch adsorption experiments were conducted at various conditions including contact time, adsorbate concentration, humidity, and temperature. The adsorption capacity was increased by raising the sorbent humidity up to 50 percent. The adsorption of t...
