Research Interests



Competence area:



Applied Inorganic Chemistry :

the synthesis and characterisation of inorganic materials;

the synthesis and characterisation of oxide precursors from the liquid phase by coprecipitation

(complexation)-flotation;

recovery of ionic, molecular species and deficit materials.



Separation and Recovery from aqueous systems of useful compounds by ion-flotation, related techniques and combinated methods :

recovery and depollution; decontamination of aqueous systems;

theoretical aspects of flotation (appearances of separation equilibrium and kinetics, main influencing factors, electrokinetic properties; new classes of collectors);

the study of surface active agents influence (STA) and of M-STA and M

-M

2

-STA;

extension of applicability area of ion flotation and its variants.

Researches concerning separation science in aqueous systems by nonconventional methods i.e. Ion-molecular flotation, sorbtion and colloidal flotation , represent a actual subject of the last 40 years in water chemistry.

The experimental results justify the interest of many specialists for this field, for the group of adsorptive bubbles techniques, flotation and its variants.

In Romania, in the Inorganic Chemistry, Phisical-Chemistry and Electrochemistry Department of the Applied

Chemistry and Materials Science Faculty, UPB, there is a researching group with such interest area from 1978, lead by

Prof.Dr.eng.

STOICA LIGIA who started the research in this particular domain in 1978 with her Eng.D thesis.

Flotation proved to be an interesting interdisciplinary research field, with many applications in depollution, recycling of useful compounds and inorganic compounds synthesis.

The systems studied are generally new, unstudied in literature and suitable for industrial application.



Main Research Activities:

1.

Applied inorganic chemistry :



Ionic species recovery (metallic cations Cu(II), Co(II), Ni(II), Cr(III), Zn(II) et al.; anions PO

3 AsO

, et al.) useful compounds (Pd, Ag) from aqueous systems by flotation variants and recycling;



The characterization of the species isolated in the separation processing;



Simple and mixed oxides precursors synthesis from the liquid phase by precipitate/complexation flotation;



Depollution of wastewaters containing toxic elements (As, Cd, Hg, Pb, Ra, Cr).

2.

Recovery proceedings in aqueous systems by flotation, related techniques and combinated methods:



Recovery/depollution;



Decontamination of ( 226 Ra);



Theoretical principles of flotation:

Equilibrium aspects and separation kinetic ;

Electro-kinetic properties;

The influence of surface active agents;

The flotation separation mechanism;

New classes of collector reagents study.



The study of M-STA and M

1

-M

2

-STA interaction using physico-chemical methods for coordinative chemistry.

The main research is concentrated on the study of some impure aqueous systems with inorganic and organic species (Cu(II), Ag(I), Cd(II), Zn(II), Mn(II), Co(II), Ni(II), Fe(III), Ti(IV), Zr(IV), Ce(III), La(III), Ra(II), Mo(VI),

Pd(II), Cr(III), dyes, detergents, petroleum products, pesticides et al.), and recycling the isolated products.



The research works were financed by grants CNCSIS and national programs ( MCT, MEN, ANSTI, INCD-ECOIND

(ICPEAR), ICPMRR, ZECASIN, UPETROM, etc.

) and were used to produce some depollution technologies.



The experience gained in solving the problems mentioned above and the collaboration with specialists from the same area from Grece, Germany, Portugal, United Kindom was used to create the monography „Ion and Molecular

Flotation” published by Editura Didactica si Pedagogica, Bucharest, 1997, (348 pag.)

P O L

I I I T E H N




The scientific papers published in various ICI revues and/or presented at different International Congresses ar

Symposiums were greatly appreciated and demanded by specialists from the same field.



In order to help the extension of this separation science domain, very complex and multy-disciplinary by the complexity of the problems to solve, and to help the future specialists interested in this field, we introduced the optional course

„Separation and recovery precesses of polutants by ion-flotation” to the V th year of Environment Protection until

2003/2004 and VI th year Advanced Studies of Faculty of Industrial Chemistry-UPB. We also provide laboratory practical works for this course.



By personal efforts and having the Inorganic Department support, we managed to create a representative group in separation techniques science, formed by experimented stuff and young scientists and students. The main works were finalised by graduation papers (1-3/year), 12 PhD thesis and 1 thesis in co-tutela supervisor.
