Biodegradable Surfactant Phosphorus Content Estimation

Project Description

URGENT
MULTIPLE TESTING
Contract chemical testing laboratory needed to test a biodegradable surfactant for cleaning range hoods to import the product:
1. Phosphorus content
Test method:
- ASTM D820-1993 (reapproved 2016) - Standard Test Methods for Chemical Analysis of Soaps Containing Synthetic Detergents
- EPA 365.1, 365.2 AND 365.3 - Determination of Phosphorus by Semi-Automated Colorimetry; Phosphorous, All Forms (Colorimetric, Ascorbic Acid, Single AND Two Reagent)
- ISO 6878: 2004 - Water quality — Determination of phosphorus — Ammonium molybdate spectrometric method
- APHA 4500-P - Standard Methods for the Examination of Water and Wastewater.

2. Ultimate aerobic biodegradability - OECD 302 (Inherent Biodegradability)

We would like to start testing asap.
Thank you.
