Abstract (PDF)
Graphical Abstract: 
The incidence and the type of acute chemical poisoning in Republic of Moldova during 2011-2015 were assessed. Records show 22458 cases of poisonings, including 919 death cases. The analysis of poisoning cases involving various types of chemical substances causing the intoxication reveals that the medicines-related poisoning accounts for the highest record of cases (6971), followed by alcohol poisoning, 6556 cases, gas poisoning is the third, with 1860 cases, and pesticide-related poisoning, with 707 cases. Age and gender characteristics of chemical poisonings and ways of exposure to chemicals are discussed.

Abstract (PDF)
Graphical Abstract: 
This paper demonstrates the possibility to use ceftriaxone (CEFTR) active compound from expired Cefort®as additive in nickel electrodeposition from Watts baths. Electrochemical behaviour and the influence of CEFTR on nickel electroplating were studied by electrochemical methods. Experimental data recommends CEFTR as additive in nickel electroplating from Watts baths.

Abstract (PDF)
Graphical Abstract:
 Comparing the problems in Romania and Senegal, regarding wastewater treatment, the present paper aims to identify the best methods and techniques to treat the municipal wastewater in small treatment plants with sequential operation. This paper examines the possibility of using Sequencing Batch Reactor (SBR) process to treat the municipal wastewater characterized by low flow. This paper also presents a comparative analysis of the degree of purification achieved in a SBR wastewater treatment plant, as well as legislative regulations in Romania and Senegal. Finally, the paper identifies the possible uses of the treated wastewater in different household activities.

SYNTHESIS AND CHARACTERISATION OF A NOVEL PHOSPHONATE LIGAND AND ITS PALLADIUM(II) COORDINATION COMPOUND

Author(s):

Olesea Cuzan


Field: Inorganic and coordination chemistry
Type: Research paper
Issue: 2017 Volume 12, no.1

Keywords: palladium, coordination compounds, phosphonate ligands, X-ray characterization.
Full Text (PDF): Download

DOI:
 dx.doi.org/10.19261/cjm.2016.370

Abstract (PDF)
Graphical Abstract:
 The novel N-(methylene-2-pyridine)-N,N-bis(diethoxyphosphorylmethyl)amine ligand (L) was obtained through a double Kabachnik-Fields reaction, starting from 2-aminomethyl pyridine (2-picolylamine). Based on the L ligand, a new palladium(II) coordination compound [Pd(L)2Cl2] has been synthetized and comprehensively characterized by spectroscopic methods (1H NMR, UV-Vis), ESI mass spectrometry and X-ray crystallography.
