BS 1016-10 describes two methods for determining the amount of arsenic in coal and coke.
BS 1016-10 is Part 10 of a series issued under the same number, BS 1016, dealing with methods for the analysis and testing of coal and coke.
BS 1016-10 on methods for determining the amount of arsenic in coal and coke is useful for:
Arsenic is added to air and the environment in general by burning coal with high arsenic concentrations. Arsenic has so many health hazards when added to food, water, air. Therefore, the determination of arsenic in coal and coke is very essential.
BS 1016-10 provides two procedures- dry and wet oxidation, for taking the sample into solution, after which the same procedure is followed in each case for the determination of the arsenic.
The methods given in BS 1016 are specified for the analysis of coal or coke or, in some instances, for the analysis of both coal and coke. It is expected that the methods given in BS 1016-10 would also be applicable to the determination of arsenic in manufactured smokeless fuels (other than coke) made by the conventional process, although no systematic survey has been made.
The revision of Part 10 has been undertaken to complete the introduction of metric units and to adopt a uniform presentation.
Note: The wet oxidation procedure and the subsequent procedure for the colorimetric determination of the arsenic are technically equivalent to those specified in ISO/R 601; however, the dry oxidation procedure differs from that in the ISO standard in the nature of the oxidants and in the maximum temperature reached.
BS 1016-10 provides you with guidance to carry out dry and wet oxidation methods for the determination of arsenic in coal and coke with precision and accuracy.
