【摘要】:以檸檬酸為原料采用水熱法制備了碳量子點(diǎn),并研究了這種納米粒子變化對光澤精化學(xué)發(fā)光強(qiáng)度的影響。實(shí)驗(yàn)結(jié)果表明,在傳統(tǒng)的光澤精化學(xué)發(fā)光體系中加入碳量子點(diǎn)能明顯抑制光澤精的化學(xué)發(fā)光強(qiáng)度,抑制信號與碳量子點(diǎn)的濃度具有相關(guān)性,并且優(yōu)化了光澤精、過氧化氫和氫氧化鈉濃度對發(fā)光信號的影響。在最佳實(shí)驗(yàn)條件下,在0.3~1.5 mmol/L碳量子點(diǎn)濃度范圍內(nèi),發(fā)光信號的減弱值與碳量子點(diǎn)濃度呈線性變化關(guān)系,相關(guān)系數(shù)達(dá)到0.9903。
[Abstract]:Carbon quantum dots (QDs) were prepared by hydrothermal method with citric acid as raw material, and the effect of the change of nanoparticles on the chemiluminescence intensity of gloss essence was studied. The experimental results show that the addition of carbon quantum dots to the traditional gloss essence chemiluminescence system can obviously inhibit the chemiluminescence intensity of gloss essence, and the inhibition signal is correlated with the concentration of carbon quantum dots, and the effects of gloss essence, hydrogen peroxide and sodium hydroxide concentration on the luminous signal are optimized. Under the optimum experimental conditions, the relationship between the weakening value of luminous signal and the concentration of carbon quantum dots is linear in the range of 0.3 鈮,
