摘要:
Cross-linked copolymers in the form of dense or porous membranes (films) and their application as colorimetric sensors of divalent metals and/or oxidising anions in aqueous media, such as for example in drinking and industrial water, and in food products. The present invention relates to copolymers cross-linked by structures of formula (I) and to processes for obtaining them.
摘要:
A method tor measuring aqueous manganese concentration includes adding a metal- ligand chelate including a chelating ligand and a metal coordinated with the chelating ligand to an aqueous sample wherein the metal of the metal-ligand chelate is other than Mn, such that the metal is preferentially displaced by MR from the aqueous sample under the conditions of reaction, and measuring the displaced metal

본 발명은 도금액에 포함된 금속성분의 액중 농도 지시체 및 이를 이용한 도금방법에 관한 것으로서, 좀더 상세하게는, 도금하고자 하는 도금금속성분의 농도가 낮아짐에 따라 상기 도금액의 색을 변화시켜 농도변화를 시각적으로 나타냄으로써 조속한 시간 내에 작업자가 용이하게 도금액에 포함된 금속성분의 농도 관리를 할 수 있다. 또한, 실시간으로 도금금속성분의 보충 여부를 판단이 가능하여 도금작업의 정밀도와 신뢰성을 향상시킬 수 있으며, 지속적인 유지관리에 따른 작업성을 향상시키고, 소요비용을 절감시킬 수 있다.
摘要:
A nanoparticle based assay for monitoring chemical reactions in real-time, ion concentrations in solution, and oxidation potential of ions in solution is describe. The assay is based on use of photoluminescent perovskite nanoparticles with the composition XYZ 3 . The XYZ 3 nanoparticles are added to a reaction or a solution to be analyzed, and the optoelectronic response of the nanoparticle is proportional to the chemical kinetics of the reaction or concentration of target. The resulting color changes can be qualitatively monitored by eye or quantitatively by spectroscopy. The assays may serve as a compliment or replacement for routine chemical analysis performed over the course of a reaction.
