General Description

Method: Colorimetric, with test strips and reagent, 10 - 25 - 50 - 100 - 250 - 500 mg/L (PO₄ ^3-), MQuant^®

The MQuant^®Phosphate test includes test strips and all necessary additional reagents. It is suitable for determining orthophosphate in wastewater, soil samples, fertilizers and food. In sulfuric solution orthophosphate ions (PO₄ ^3-) react with molybdate ions to form molybdophosphoric acid, which is reduced to phosphomolybdenum blue (PMB). The phosphate concentration is measured semi-quantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale. The test strips are perfect for pre-testing a sample in an economic and quick way to estimate the phosphate concentration and a possible dilution factor prior to using a quantitative method such as a Reflectoquant^®or Spectroquant^®Phosphate test.

Application

• Effects of Two Remineralizing Agents in Combination with Er:YAG and CO(2) Laser Irradiation on Microhardness of Demineralized Enamel: This study highlights the use of phosphate tests in dental research, specifically in measuring the efficacy of remineralizing agents combined with laser treatment to enhance enamel hardness, which is crucial for dental health and preventive care (Mapar M et al., 2024).



• Zinc and Silicon Nano-Fertilizers Influence Ionomic and Metabolite Profiles in Maize to Overcome Salt Stress: This research utilizes phosphate tests in the study of plant physiology, specifically to gauge the efficacy of nano-fertilizers in enhancing phosphate uptake under salt stress conditions, providing insights into sustainable agricultural practices (Shoukat A et al., 2024).



• Investigation of Mechanical Properties of Polymer-Infiltrated Tetrapodal Zinc Oxide in Different Variants: Applies phosphate testing in the field of materials science to assess the interaction of phosphate with novel composite materials, thereby informing the development of more durable and efficient materials for various industrial applications (Scherer F et al., 2024).
