“…After, carbon was measured again (TIC) and the TOC was calculated by the difference of TC and TIC. Phosphorus, potassium, magnesium and calcium in digested plant materials were diagnosed according to Schramel et al (1993) using inductively coupled plasma spectrometry (ICP-AES -Unicam iCAP6000 Duo).…”

. Impact of P fertilisation on the growth performance of black locust (Robinia pseudoacacia L.) in a lignite post-mining area in Germany. Ann. For. Res. 58(1): 39-54.Abstract. Due to its ability to grow on marginal sites black locust (Robinia pseudoacacia L.) has been widely planted as a short rotation coppice (SRC) system that produce a renewable biomass feedstock in several post-mining areas of East Germany. However, as most of these sites are still in an initial stage of reclamation with low humus and nutrient contents, phosphorous can play a significant role as a plant limiting factor, because legumes require more P than other plants for their development. In April 2011, two experiments were conducted to evaluate the influence of higher rates and different applications of phosphorus fertiliser on the nutrition, survival, and biomass production of two different-aged black locust SRC plantations on the post lignite-mining site "Welzow-Süd", situated in NE Germany. Treatments were applied as triple superphosphate (30, 60 and 120 kg P ha -1 ) and PK fertiliser (60 kg P ha -1 ) through broadcasting or banding on recently harvested or planted trees, respectively. Soil, leaf and woody biomass data were analysed utilising the Mann-Whitney U test and the Spearman correlation coefficient (rS). Following two growing seasons, it was observed that the total dry weight yields of the black locust seedlings were increased strongly by up to 8 times when compared to the control group, particularly when TSP was applied through banding. P fertilisation, however, did not affect the biomass yield of six-year-old black locust trees, but P concentration in leaves among treatments of both sites was still significantly increased and sufficient from a quantity upwards of 60 kg P ha -1 . Taken together, a comparably moderate amount of P fertiliser (60 kg ha -1 ) had a strong impact on P uptake and growth performance in the examined black locust seedlings, which reveals a high potential to improve the current fertilisation practices for SRC black locust plantations grown on our research site.

“…The adsorption capacity of Cell-PAB was determined at 298 K, using the batch technique 1 . About 100 mg of Cell-PAB were mixed with 50 mL of aqueous solutions of the metal under study (concentrations between 2.0 × 10 -4 and 2.5 × 10 -3 mol/L) and the resulting mixture shaken for 10 min.…”

“…Preconcentration by separation of dissolved trace element ions onto a chemically modified solid support has been studied intensively in recent years [1][2][3][4][5][6][7][8][9][10][11][12][13] . Cellulose is a particularly attractive solid support because of its mechanical and chemical stability and its availability in pure and diverse physical forms.…”

“…The principal success of this solid modified support with organofunctional groups is the immobilization of the desired reactive atomic group, which renders this surface highly versatile in developing various functions 13 . Thus, functional groups containing nitrogen 1,2 , sulfur 9 , oxygen 3,4 and phosphorus 6 arranged in cellulose chains render the surface useful for a variety of academic and industrial applications. Moreover, the majority of these anchored molecules contain nitrogen or oxygen or a combination of the two, which can bind metal ions in mono-or polydentate fashion [1][2][3][4]7,10,12,13 .…”

Synthesis, characterization and determination of the metal ions adsorption capacity of cellulose modified with p-aminobenzoic groups

This paper describes the synthesis and characterization of p-aminobenzoic modified cellulose (Cell-PAB), as well as the separation and preconcentration of Cd(II), Cu(II), Ni(II), Pb(II) and Zn(II) ions from an aqueous medium using a Cell-PAB bath and the column technique. The quantity of p-aminobenzoic groups attached to the cellulose surface, i.e., 1.81±0.04 mmol/g, was determined by elemental analysis. The FT-IR spectra of Cell-PAB revealed characteristic bands of paminobenzoic groups, indicating the desired functionalization of the cellulose surface. The adsorptive capacities for the metals (Ns) Cd, Cu, Ni, Pb and Zn (Ns) were, respectively, 1.72 ± 0.02, 1.96 ± 0.02, 1.88 ± 0.04, 2.01 ± 0.03 and 1.93 ± 0.03 mmol/g. Metal separations performed in flow experiments using a column packed with 1 g of Cell-PAB and 5 mL of 1.5 mol/L HCl solution as eluent achieved an almost 100% metal ions recovery rate.
