Pre-concentration and spectrophotometric determination of Co(II) by adsorption of its (E)-N1-((1-thiophen- 2- yl) ethylidene) benzene-1,2-diamine complex on an alumina column

A simple method was developed for the pre-concentration of Co(II) based on the adsorption of its (E)-N1-((1-thiophen- 2- yl) ethylidene) benzene-1,2-diamine complex on a neutral alumina column. The influence of acidity, eluting agents, stability of the column, sample volume and interfering ions was investigated in details. The adsorbed complex could be eluted using environmentally benign polyethylene glycol (PEG 400)...

Study of the seasonal variations in Turag river water quality parameters

The purpose of this study was to assess the degree of pollution of Turag river water by determining various physico-chemical parameters. Water samples were collected six times per year during wet and dry season at the following three locations: Tongi Railway Bridge, Bishwa Ijtema field and Ashulia. Most of the measured physicochemical parameters exceeded permissible limit of drinking water. The recorded pH ranged from...
