Foreword
This standard is formulated with a view to implementing the “Environmental Protection Law
of the People’s Republic of China” and the “Law on Prevention of Air Pollution of the People’s
Republic of China”, protecting the environment, guaranteeing the human health, controlling the
emission of motor vehicles, and regulating the determination methods of platinum (Pt), palladium
(Pd) and rhodium (Rh) loading in vehicle-used ceramic catalytic converters.
This standard specifies inductive coupled plasma-optical emission spectrometry (ICP-OES)
and inductive coupled plasma-mass spectrometry (ICP-MS) for the determination of Pt, Pd and Rh
loading in the vehicle-used ceramic catalytic converters.
This standard is issued for the first time.
This standard was organized and formulated by the Department of Science, Technology and
Standards of Ministry of Environmental Protection.

Warning. Since hydrochloric acid, nitric acid, hydrofluoric acid and perchloric acid are
highly corrosive and pungent, protective devices shall be worn as required when handling any
of them in fume cupboard, so as to prevent acid mist from flowing into the respiratory tract
and contacting with skin or clothing. If any contact is caused due to carelessness, emergency
measures shall be taken immediately. Upon detection, any residue and raffinate shall subject
to safety treatment.
1 Application Scope
This standard specifies inductive coupled plasma-optical emission spectrometry (ICP-OES)
and inductive coupled plasma-mass spectrometry (ICP-MS) for the determination of platinum (Pt),
palladium (Pd) and rhodium (Rh) loading in the vehicle-used ceramic catalytic converters.
This standard is applicable to the determination of Pt, Pd and Rh loading in catalytic converters
with cordierite honeycomb ceramics as the carrier and precious metal as the active constituent.
Weigh 1g sample before digesting and scaling it to 100mL; then, analyze and determine, by
ICP- OES, the detection limit and lower limit which are 5μg/g and 20μg/g respectively; if by
ICP-MS, the detection limit and lower limit are 0.005μg/g and 0.02μg/g respectively.
2 Normative References
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this standard. For undated references, the latest edition applies.
GB/T 6679 “General Rules for Sampling Solid Chemical Products”
GB/T 6682 “Water for Analytical Laboratory Use—Specification and Test Methods”
GB/T 8170 “Rules of Rounding Off for Numerical Values & Expression and Judgment of
200℃ for 2h before taking out and cooling it until room temperature.
7.3 Weight the Carrier Mass
Weight he catalytic converter carrier on an electronic balance (6.6), accurate to 0.01g.
7.4 Measure the Carrier Volume
The volume of carriers in different shape is measured by the following three methods.
a) For regular carrier (such as cylinder or runway column)
Use, in different positions, a vernier caliper to measure their volume parameters respectively
from twice to 4 times, and take their average to calculate the carrier volume and round off it to a
4-digit effective figure according to GB/T 8170.
b) For regular carrier whose sectional area is to calculate
Take three A4 papers or above with uniform texture, use a paper knife to cut the same part on
A4 paper along the cross section of carrier, and then weigh, on the analytical balance, each A4
paper and the same part on the sectional area of carrier respectively, accurate to 0.000.1g. Then,
calculate the average sectional area of carrier according to the proportional relation between the
paper mass and the paper area. The relative deviation of each measurement and average shall be
less than 0.5%. The carrier length is measured by a vernier caliper and the carrier volume is the
product of its sectional area and length.
c) For irregular carrier
Seal the catalytic converter carrier with a preservative film and place it into a vessel filled with
water. Then, collect the overflowed water and weigh the water mass. The carrier volume is
calculated through dividing the water mass by the water density.
7.5 Crush, Grind and Split the Sample
Crush the sample to about 1mm in grain size, split it once or more with a sample splitter (6.1),
and then use a grinder (6.2) to grind the split sample into powder with the grain size less than
0.075mm.
