Adsorption
ISBN: 9783659669057 / Angielski / Miękka / 2015 / 164 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Saw dust is a byproduct of carpentry and saw mill industries and is available in abundance. In this study Saw dust of Morus alba was used for the Adsorptive removal of metal ions from aqueous solution onto low cost biosorbent with respect to adsorption kinetics and isotherm. The adsorption of heavy metals was carried out as a function of shaking time, concentration of adsorbate and adsorption temperatures. In the initial fifteen minutes the adsorption was rapid and then it slows down due to the diffusion of metals ions in the porous texture of biosorbent and then reached to plateau....

Adsorption Studies of Aliphatic Organic Acids on Activated Carbon
ISBN: 9783848488544 / Angielski / Miękka / 2012 / 192 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Wood of Prunus persica was utilized for the preparation of activated carbon. The carbon was characterized by pH, moisture content, ash content, bulk density, surface area (BET), FTIR and EDS. The BET (m2/g) surface area analysis of the carbon samples activated at 800 oC showed high surface area. FTIR analysis showed that the carbon surface carried the oxygen containing functional groups, which disappeared at high activation temperatures. The EDS analysis showed high carbon contents in the sample activated at high temperature as compared to Raw and 300 oC activated samples while the contents...

Variation of Contaminants in the Road Side Agricultural Soil
ISBN: 9783848415380 / Angielski / Miękka / 136 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Soil comprising the pedosphere is positioned at the interface of the lithosphere and biosphere with the atmosphere and hydrosphere. Soil is considered a three phase system, consisting of solid, liquid, and gas. The solid phase consists of mineral and organic matter, including living organisms. The liquid phase is known as the 'soil solution', and is the phase from which plants take up nutrients. The gaseous phase is important for supplying oxygen to the roots for respiration. Agrictural soil of the study area is very fertile and is a main source of economy for local population. This deals the...

Investigation of Essential Nutrients in Oryza Sativa (Rice)
ISBN: 9783846554746 / Angielski / Miękka / 2011 / 176 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Rice is a cereal foodstuff which forms an important part of the diet of many people worldwide. Domesticated rice comprises two species of food crops in the Oryza genus of the Poaceae ("true grass") family, Oryza sativa and Oryza glaberrima (Crawford et al., 1998). Rice is grown as a monocarpic annual plant, although in tropical areas it can survive as a perennial and can produce a ratoon crop and survive for up to 20 years (International Rice Research Institute 2008). Smith et al (1998) reported that Rice provides more than one fifth of the calories consumed worldwide by humans. In the...

Heavy Metal Concentrations in the Muncipal Water Sewage
ISBN: 9783659002113 / Angielski / Miękka / 2012 / 128 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Water samples were collected from different localities of Mingora Swat, Pakistan and were analyzed for both physical and chemical parameters. The results show that the sample area is moderately polluted and the source of pollution is the municipal sewage of the local community located around the Mingora Khuwarr. The water of Mingora Khuwarr then joins the main Swat River which is a main source of drinking and irrigation for the lower Swat. However due to dilution factor the concentration of pollutant further decreases in the bulk water and thus its toxicity also decreases. However the water...
