Precipitation and Co-precipitation

Precipitation and Co-precipitation

Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...

Area of Science:

Environmental Science
Analytical Chemistry
Sensor Technology

Background:

Traditional Total Dissolved Sulfide (TDS) measurement requires pH monitoring or sample acidification.
Direct in-situ measurement of TDS in aquatic media is challenging.

Purpose of the Study:

To develop a novel microsensor for direct, in-situ measurement of Total Dissolved Sulfide (TDS).
To eliminate the need for simultaneous pH monitoring in TDS analysis.

Main Methods:

Utilized an amperometric H2S microsensor integrated with an acidic chamber for in-situ conversion of sulfide species.
Characterized sensor performance including response time, linear range, sensitivity, and long-term stability.
Applied the microsensor to resolve microscale TDS gradients in natural sediments.

Main Results:

The microsensor achieved a response time of <50 s and a linear range of 0.5–650 μM.
Demonstrated stable sensor performance with no noticeable change in zero current or sensitivity over 7 weeks.
Successfully resolved microscale TDS gradients in freshwater and marine sediments.

Conclusions:

The developed microsensor offers a direct and efficient method for TDS measurement in aquatic environments.
Potential applications include environmental monitoring of sediments and online monitoring of industrial and urban sewers.
