Abstract

The present disclosure discloses a process that determines the presence of phosphonate in saline water without specific equipment and can be used with simple resources if necessary. The process is carried out in two parts: 1) conversion of phosphonate by thermal method, and 2) determination of phosphate applying the analytical method based on digital images (DIA). Furthermore, the process for detecting phosphonates was developed with the concept of a portable analytical method capable of being performed even by analysts without training in chemical operations.

Claims7

Dependent claims

A process for determining phosphonate in saline water, the process comprising the steps of:

converting the phosphonate by a thermal method, the thermal method comprising:
transferring a sample to be analyzed to a crucible with a lid, the sample comprising phosphonate;
heating the sample in the crucible with the lid half open in a muffle;
and
transferring the crucible with the lid closed to a desiccator;
recovering cold residue from the converting the phosphonate step with pure water;
and
determining phosphate by applying an analytical method based on digital images.
