Sewage sludge is regarded as a potential source for soil fertilizer However, the direct utilization of sewage in agricultural land restricted since it also contains heavy metals, pathogens, and toxic compounds. Pyrolysis destroys organic pollutants partly volatilizes metals. In this study, pyrolysis was carried out order to determine optimum residence time temperature recover phosphorous remove...

A general method of automated multidimensional fractionation has been developed. Its basic ingredients are: (a) cascade fractionation, i.e., the sequential fractionation of components obtained from each chromatographic dimension on the same or a different dimension, (b) on-line acquisition and processing of data at each stage in the fractionation procedure, (c) a method for determining the begi...

Coordinative chain transfer polymerization (CCTP) has opened a new path for the development of novel products like olefin block copolymers and chain-end functional polyolefins. However, conflicting results are frequently reported on the catalyst performance including activity and comonomer selectivity under CCTP conditions. Here we have selected two catalysts including rac-ethylenebis(1-η5-inde...

Zinc and Ni are essential micronutrients whose stable isotope systematics in marine sediments represent promising, but still developing, tracers of past ocean chemistry biology. Sediments from upwelling continental margins have been identified as important sinks for Zn Ni, driven by high productivity, incorporation the metals into cells organic carbon burial. At present, however, our understand...

A series of laboratory studies were conducted to increase understanding of stable carbon (C/C) and hydrogen (D/H) isotope fractionation arising from methanogenesis by moderately thermophilic acetateand hydrogen-consuming methanogens. Studies of the aceticlastic reaction were conducted with two closely related strains of Methanosaeta thermophila. Results demonstrate a carbon isotope fractionatio...

Abstract Collagen extraction from bones or dentine, commonly used for radiocarbon ( 14 C) dating and stable carbon nitrogen isotope (δ 13 C δ 15 N) analyses, involves the dissolution of bioapatite skeletal elements. This fraction is typically disposed during pretreatment. Here, we test possibility utilising this dissolved mineral solution analysis zinc composition 66 Zn). Bioapatite Zn a novel ...
