Wed 28 Apr 2021 11:56:04 SAST ]]> Surface studies of a biomaterial for the development of a biosensor for the detection of trace metals. 5.5, and these amount to Zeta potential of 0 to ±5mV. High-resolution scanning electron microscopy (HRSEM) reveals a microstructure showing predominantly flattish rod like particles. Energy dispersive xray (EDX) shows high percentage levels of Al, Mg and Si with potential to form organometallic compounds. The presence of amino groups would form a linkage entry of the enzyme into MT.cellulosic surface hydroxyl groups. Maize tassel (MT) has shown its potential to adsorb trace metals from aqueous solution [2-4]. But before MT can be put into use in biosensor development, its characteristics properties such as morphology, dispersion and adsorption trends need to be known. In the current study, we present the aforementioned properties of MT. It is anticipated that these factors would enhance the integration and coordinated participation of the enzyme during catalysis.]]> Wed 24 Mar 2021 14:19:25 SAST ]]> Improved derivatisation methods for the determination of free cyanide and cyanate in mine effluent.

The observed positive correlation may suggest a possible influence of trace metals on PBDE concentrations in leachates. Furthermore, a test of relationship between major anions and PBDEs yielded p=0.21), Br− (r=0.6, p=0.29) and NO3 (r=0.96, p=0.08) with an insignificant statistical difference. However, evaluation of the relationship between some water quality parameters (pH, dissolved oxygen and electrical conductivity) gave negative correlation with PBDE concentrations.]]> Tue 13 Mar 2018 11:54:37 SAST ]]> Polybrominated diphenyl ethers in car dust in Nigeria: Concentrations and implications for non-dietary human exposure.
