Lidia Petkova Ivanova currently works at the Institute of General and Inorganic Chemistry, Bulgarian Academy of Sciences. Lidia does research in Biosorption and Analytical Chemistry. Their most recent publication is 'Characterization of Two Bulgarian Herbs for Use as Biosorbents for Copper(II)'.
The aim of the present study is the effective application of chemometric approach to the elemental composition of a data set of ten ethereal oil plant materials. The contents of 28 essential and toxic mineral elements at main, minor and trace level are determined in each sample by means of direct solid sampling electrothermal vapourization inductiv...
The efficiency of a material based on the plant Thymus vulgaris L. for Cu(II) removal from aqueous solutions is investigated. The estimation of optimal parameters influencing the Cu(II) adsorption was studied by the batch method. Optimum pH value was found to be about 4. Kinetic of Cu(II) adsorption was very fast. Equilibrium experimental data were...
The objective of the present study is the characterization of an adsorbent plant material based on Hypericum perforatum L. and the investigation of its feasibility for the removal of Cu2+ ions from aqueous solutions. XRD, TGA, FTIR, SEM and low-temperature nitrogen adsorption were used for the analytical characterization of the material. Particle s...
The content of essential, non-essential and toxic elements in seven commercially available and widely consumed for medicinal purposes Bulgarian herbs was determined by means of an optimized electrothermal vaporization induc-tively coupled plasma optical emission spectrometric (ETV-ICP-OES) method in one run. Plasma observation was axial and torch a...
Two biomaterials based on the abundant Bulgarian medicinal plants Mentha spicata L. (denoted as MS) and Ruta graveolens L. (denoted as RG) were investigated as environmentally friendly biosorbents for Cu(II) removal from aqueous solutions. Grain size distribution, slurry pH, texture parameters, thermal behavior and mineralogical composition of MS a...
The feasibility of using Mentha spicata L. (MS) and Ruta graveolens L. (RG) for the removal of Cd²⁺ions from aqueous solution was investigated. Batch experiments were performed to evaluate the effect of contact time, acidity and initial metal concentration on Cd²⁺removal from aqueous solutions. Equilibrium experimental data were fitted to linear La...
The complexity of fluid inclusions in minerals as an analytical object has led to the development of several analytical methods to address this issue. The aim of the present study was to specify the field of application of the Decrepitation-Inductively Coupled Plasma Spectroscopy (D-ICP) technique in comparison with the other contemporary methods o...
