Abstract

Modification of synthesis of nanoparticles with L-Cysteine functions as a capping agent/stabilizer, so that the nanoparticles can last longer. Modification of nanoparticle synthesis by adding L-Cysteine to AgNPs and homogenizing it using a magnetic stirrer. Modification of nanoparticles (AgNPs) was monitored by observing the visible uptake. The results showed that the absorbance value increased by indicating the concentration of L-cysteine 5×10-5; 6×10-5; 7×10-5; 8×10-5; 9×10-5; 1×10-4 and the volume of L-cysteine is 4 mL.

Abstract

Silver nanoparticles with a size of 1 to 100 nm with unique properties have many advantages that they are widely applied in the medical and industrial fields. Various methods can be carried out in synthesizing silver nanoparticles both physically, chemically and biologically. In the chemical method, it is done by reducing Ag+ ions into silver nanoparticles so that this method depends on reducing agents and stabilizers used. The use of different reducing agents greatly affects the size of the nanoparticles produced. Based on the literature review, sodium borohydride (NaBH4) has a strong ability to reduce Ag+ ions into silver nanoparticles become a small size. In addition, referring to previous studies if modified with L-cysteine, the silver nanoparticles formed can be stable for more than 2 months at room temperature storage. L-cysteine-modified silver nanoparticles from previous studies were used for colorimetric analysis of vitamin B1 detection in food and water samples, where the color change in silver nanoparticles from yellow to colorless showed remarkable chemical sensor selectivity for detecting target analytes.

Abstract

Synthesis of silver nanoparticles (AgNPs) with the addition of Trisodium citrate 1% as a reducing agent and stabilizer in AgNO3 by chemical reduction. The obtained AgNPs were characterized using UV-Vis Spectrophotometer, PSA (Particle Size Analyzer) and TEM (Transmission Electron Microscopy). Concentration optimum gNPs is 1 mM AgNO3 with the addition of 6 mL of Trisodium citrate 1% at heating temperature 85OC for 13 minutes stirring. Characterization of AgNPs with TEM resulted in average particle size of 46,5 nm with various shapes of triangels, rectangles, hexagons and rounds. The synthesized silver nanoparticles (AgNPs) were used for analysist chloramphenicol. The measurement results of the calibration curve show that the linear equation y = 0,0078x + 0,8623 with a correlation value of r 0,9954. The results of the validation form precision values is 0,54759 % has met a good precision, namely KV 2%.

Abstract

Preparation and characterization of Cu(II) ion selective electrode membranes based on polyvinyl chloride (PVC) using sodium sulfide (Na2S) as the ionophore has been done. The use of PVC polymer functions as a material that strengthens the properties of the membrane mixed with Na2S to form a homogeneous membrane and can reduce the risk of leaks in the membrane used. However, PVC has stiff properties, so a plasticizer in the form of DOP was needed to reduce intermolecular forces and make the membrane elastic. The preparation was carried out with the composition Na2S : PVC : DOP, namely 6 : 3 : 1. The membrane was doped with CuSO4 solution for 7 days and the Cu2+ ESI performance was measured to increase the optimal conductivity of the membrane, it is done by doping the membrane, namely by inserting 1 M Cu2+ dopant metal. The ESI Cu2+ performance results show a solution composition of 1:2 CuSO4:KNO3 and works well in the composition range 10-5 - 10-1 M, with a Nernst factor value of 28.9 mV/decade and a detection limit of 1.01×10-5 M. The response time of ESI Cu2+ was 10-60 seconds and can be used for 3 days. ESI Cu2+ works in the pH range 4-6 and the presence of interfering ions Cd2+, Zn2+, Cl-, NO3- and SO42- does not affect the performance of ESI Cu2+.
