GB/T 36690-2018Method of determination for 26 elements (copper，nickel，lead，zinc，cadmium，chrome etc.) content in the sludge from industrial waste liquid treatment (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

1 Scope

This standard specifies the terms and definitions of methods for determining the content of 26 elements such as copper, nickel, lead, zinc, cadmium and chromium in industrial waste liquid treatment sludge. General provisions, sample preparation and inductively coupled plasma atomic emission spectrometry and hydride generation atomic fluorescence spectrometry.

This standard applies to industrial waste liquid treatment sludge in silver (Ag), aluminum (Al), arsenic (As), gold (Au), barium (Ba), beryllium (Be), barium (Bi), calcium (Ca), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), mercury (Hg), manganese (Mn), molybdenum (Mo), nickel (Ni), palladium (Pd), lead (Pb), Determination of total content of 26 elements of antimony (Sb), selenium (Se), tin (Sn), antimony (Sr), titanium (Ti), vanadium (V), and zinc (Zn).

Inductively coupled plasma atomic emission spectrometry for the determination of concentration of fresh sludge samples without dilution of the sample solution The range is from 5mg/kg to 10000mg/kg; the suitable concentration range for air-dried or dried sludge samples is from 50mg/kg to 100000mg/kg.

The detection limits of each element in inductively coupled plasma atomic emission spectrometry are shown in Appendix A.

The detection limit of mercury by hydride generation atomic fluorescence spectrometry is 0.004mg/kg, and the suitable concentration range is 0.016mg/kg~ 5mg/kg; the detection limit of arsenic, selenium, tellurium and strontium is 0.020mg/kg, and the suitable concentration range is 0.080mg/kg~50mg/kg.
