You can use technical analysers like Atomic Absorption  or ICP OES , that depends what detection limits are you looking for.

Thank you sir.

you can measure Lead and Copper by spectroscopy method ( refer APHA book) 

Thank you Mathuraman Sir.

I would use ICP-OES as suggested by Philip Delrue and compare with guideline values

you can determined lead and copper ion by AAS or ICP-Ms

Use a graphite furnace attached AAS

Thank you all

If you have chance to use ICP-MS, prefer to use it. since you can measure both elements at the same time with shorter time and less effort. If you  use graphite furnace you need to measure each element separately! However, both methods have low detection limits which is good for you. 

The answer depends on how much accuracy you need your results. For ppm results you can use ion chromatography, or routine analytical chemistry methods or normal atomic absorption. For higher accuracy ppt you can use Atomic absorption spectrophotometery AAS .

For enviaronmental purposes GFAAS is the technique more used.

Generally spectrophotometric methods especially atomic absorption and others.

Thank you very much

ICP-MS is nowadays considered the method of choice if you want to measure a range of metals, but graphite furnace atomic absorption spectrometry give excellent results and if you only need to measure Cu and Pb I would certainly recommend GP-AAS which give accurate and precise results at relatively low cost. For large sample volumes you may need automatic injection on your AAS.

Do the acid digestion (hot plate or microwave) and analyses by flame AAS or ICP. If need high accuracy, use ultra-pure acids for digestion followed by analysis using AAS having Graphite furnace. For lower concentration determination, spiking with know concentration will be required. Check the accuracy of analysis using internal quality control samples or using standard reference materials.

For lower concentration determination. Check the accuracy of analysis using internal quality control samples or using standard reference materials and  analyses by flame AAS or ICP.

Depends on what resources are available to you: ICP-MS is perfect but expenisve. But even if resources are limited there are a number of suitable spectrophotometric methods available for your purpose, all easy to find in the internet!

You may complex 100-200 ml with ammonium pyrrolidindithiocarbamate at H 4-5

and extract with 10 ml MIBK. Then use flame AAS . It also complex Cd.

If you have AAS, then at first water samples should be filtered, acidified, then you can do preconcentration using hotplate (lets say 250ml_>25 mL). Then might be used FAAS Or GF-AAS. You can use ICP-MS in case of low concentration.

Thanks a lot

Dear Jaysukh B Kathiriya

I have glad welcome with you

I invite you to submit paper for publishing in journal

You can in two way do that. Using atomic absorption and using kit  in this.

Hello Jaysukh

Your question seems to be a bit vague. What do you mean with „Lead & Copper impurities in water“.  The choice of an analytical method depends on the understanding. The bulk of these elements sticks to particulates (including colloids) which are suspended in water, and so the amount of particualtes may control nearly totally the amount of impurities in water. The definition of impurities in water should consider this background and in order to compare different water samples on the degree of cotamination  specific filtration is crucial (0,2 µm or 0,45 µm; prior to acidification). In the case of filtered samples you need analytical methods of high sensitivity, which was already pointed out (ETAAS, ICP-MS). Normally, the concentrations in particulates are much higher and so flame-AAS or ICP-OES should do (after aqua regia digest oft he filter residue). The additional analysis of element conentration bound to particualtes could help to understand the question of impurities in water much better. If this discrimination is necessary or not depends on the use of water (drinking water, irrigation water, waste water treatment, etc.).

Good luck and I wish you a happy 2016

Dear Jaysukh,

Just go to atomic absorption and measure the concentration of Copper and lead in water then compere with standard and to find the condition of water.

Dear Jaysukh

The best analytical method is ICPMS. befor you are feeding the water sample to 

ICPMS check the TDS.

OK Thank you very much Seyed Hadi & Suresh Kumar Kolli

The best way is to do acid digetion of a suitable portion (100ml) of the water sample followed by AAS analysis. If concentration of both the metals are too low, try to analyze using AAG graphite furnace. One more thing you can try is the spiking of your samples with known concentration of both the metals.

At the time of samples collection acidify samples with HNO3 (CONC) high purity approximate less than 2pH. Filtered the samples with 0.2mu filter paper. dilute if high TDS, then analyze either ICP or ICPMS using atleast 6 different concentration of standard with zero stanadrds. Insha Allah you will get good results

once you check TDS level in water and add Conc.HNO3  and analysis any one of instrument like AAS,ICP-OES(axial),ICP-MS 

For Pb and Cr estimation , you have 2 option 

1st: using the colurimetric method you can chek by water analyser

2nd : after acidified the sample it can chek by ICP MS or MP AES technics

Hello Dr Kathiriya,

Generally for metallic elements we use spectrometer methods which need an acidification (mineralization) of  samples prior to their analysis. the accuracy of this analysis depends on the kind of your device (apparatus).

Ypouy may use AA in flame. You need complex 100 -200 m with pirrolydindithio carbamete at pH  around 4-4,5 and extract qith 10 ml MIBC. Copper complesx is yelloiw.; lead comples ,no colour..

The analysis for Lead on AAS does not giving the better results, ICPMS is better option for metals in lower concentration.
