Introduction

Analysis of the core content of the standard

This standard aims at the recovery and treatment of waste palladium carbon catalyst, and establishes a complete technical system from incineration tray pretreatment to laboratory analysis, focusing on solving the problems of representative sampling and uniform sample preparation in the process of precious metal recovery.

Comparison of key technologies

Process links	Traditional methods	This standard method	Improvement advantages
Incineration enrichment	Direct high-temperature incineration	Stage-controlled temperature incineration	Reduce palladium volatilization losses
Sampling method	Simple random sampling	Grid distribution + rotation reduction	Representativeness increased by 30%
Sample preparation particle size	0.15mm standard sieve	0.106mm standard sieve	Improved detection accuracy

Implementation points

Typical application scenarios

A case study of the treatment of waste palladium carbon catalyst (water content 28%) in a pharmaceutical company:

Load according to the capacity of the incineration tray, and control the thickness at 15cm
Use a two-stage drying method (first dehumidify at 105℃, then preheat at 750℃)
Finally, the ground slag is grid-reduced three times to obtain analysis samples

Standard Evolution Analysis

This standard systematically regulates the waste palladium carbon for the first time:

Fire enrichment process parameters (temperature gradient, incineration time)
Sintered metal block treatment method (aqua regia digestion + pipette sampling)

Environmental control requirements (in compliance with GB18484 hazardous waste treatment standard)

Operation risk prompts

Key safety control points:

Risk links Protective measures Monitoring indicators

Spontaneous combustion stage Special fireproof compartment CO concentration <50ppm

High temperature grinding Fully enclosed ball mill Dust concentration＜1mg/m³
