“…Several methods have commonly been applied for lead detection including flame atomic absorption [7][8] , inductively coupled plasma -atomic emission spectrometry 9 , spectrophotometry 10 and electrothermal atomic absorption spectrometry [11][12] . However, these methods have a greater cost, higher sample volume requirement and instrumentation complexity limiting.…”

Resonance light scattering (RLS) probe for sensitive determination of heavy metals such as lead (Pb) based on diethyldithiocarbamate (DDTC) doped graphene quantum dots (GQDs) is subject to approach on green procedure of metal complex nanoparticles. Regarding Pb(II), the RLS intensity of GQDs-DDTC increases linearly by an enhancement mechanism. Interactions between target analyte and the ligand doped nanoparticles lead to an aggregation of the complex particles to form bigger volume of the metal complex. Thus, it can be used as the RLS probe for such determination of lead ion at ultra-trace level, certainly under the optimum conditions; such experimental parameters including each of DDTC and GQDs concentration, pH of solution, ionic strength, masking agent, and interfering ions are investigated in details. The methods can then be implied for selective determination of some relevant toxic heavy metals in water, foods or environment samples.

“…Therefore it is very significant to examine the trace levels of it in environments [2].Presently, the mostcommon analytical methods for the determination of trace amount of lead are the flame atomic absorption spectrometry (FAAS) [3]. The electrothermal atomic absorption spectrometry (ETAAS) [4]and the inductively coupled plasma emission spectrometry (ICP) [5]. Flame atomic absorption spectrometry is by far the most commonly employed technique for analyte determination [6].…”

A cloud point extraction (CPE) method was developed for the separation and preconcentration of trace amounts of lead is combined with flame atomic absorption spectrometry (FAAS) to determine trace amounts of lead in brine water. The method is depended on the formation of the hydrophobic complex between Pb(II) and (APDC) followed by its extraction into a Triton X-114 using surfactant. The parameters such as pH of sample, concentrations ofAPDC and Triton X-114, equilibrium temperature, and equilibrium time, which affect both complexation and extraction, are optimized. Under the selected optimum conditions, and use of matrix modifying agents enable us to develop the direct method for determination Pb in brine water. The accuracy of the method was % (96)while the detection limit was found to be (0.1122 ppm) for preconcentration of 1.0 ml sample,for the determination of Pb(II) is obtained.

In this method to amounting of the trace amount of Cu (II) ions in aqueos Samples by CNT modified Amino-pyrrolidine dthiocarbamate (APDC) which in order to improve the performance of extraction and preconcentration was used. Amounting of the ions density in solution was performed by the method of flame atomic absorption spectrometry. The effective parameters on extraction such as: effect of pH, the amount and eluent solvent, time of extraction and effect of other cation were optimized. Concentrate factor was found 57 and LOD method of limit of detection was found to 0. 6µg.L -1. the relative standard deviation is 0.76% (RSD%).
