Deteksi Metil Paraben secara Voltametri Menggunakan Elektrode Pasta Karbon

نویسندگان

چکیده

Penggunaan metil paraben sebagai pengawet telah banyak digunakan pada berbagai bidang industri, antara lain: industri makanan, kosmetik, dan farmasi dengan batas penggunaan yang diatur oleh setiap negara lembaga. Sampai saat ini, pengukuran umum dilakukan adalah menggunakan spektrofotometri UV/Vis HPLC, namun kedua metode tersebut membutuhkan waktu preparasi analisis cukup lama. Metode alternatif dapat untuk deteksi secara cepat, mudah, sederhana elektrokimia elektrode pasta karbon sampai ini belum pernah dilaporkan. Pada penelitian pendeteksian kerja. Pembuatan elektroda grafit parafin perbandingan berat sebesar 70:30. Studi terhadap kalium ferisianida 1 mM dalam 0,1 M KCl scan rate 200 mVs-1 menunjukkan puncak arus oksidasi 8,25 µA sedangkan reduksi -9,55 µA. yakni Cyclic Voltammetry (CV) Linear Sweep (LSV). Hasil LSV didapatkan rentang linieritas konsentrasi – 60 nilai r 0,993 persamaan grafik diperoleh yaitu y = 1,055x + 29,910. Limit limit kuantisasi berturut-turut 0,091 0,300 mM. bahwa voltametri dijadikan mendeteksi paraben.

The Paraben Debate

This toxicology update reviews research over the past four years since publication in 2004 of the 1⁄4rst measurement of intact esters of p-hydroxybenzoic acid (parabens) in human breast cancer tissues, and the suggestion that their presence in the human body might originate from topical application of bodycare cosmetics. The presence of intact paraben esters in human body tissues has now been c...

Microstructural Studies of Pasta and Starch Pasta

The processing methods for mung bean starch noodles were used to form “starch pasta” from various isolated wheat starches. The objective of this research was to evaluate the changes in the surface and internal structure of pasta and “starch pasta” made from various flours and wheat starch before and after cooking. Cooked “starch pasta” revealed a honeycomb-like internal structure similar to coo...

4-(2,4-dichlorophenoxy)butyric acid (DPBA) was intercalated between the interlamellae of Zn/Al layered double hydroxides (LDHs). Two methods of intercalation were adopted, (a) direct synthesis by co-precipitation of metal nitrates and DPBA and (b) ion exchange of LDH nitrate with the organic anion. The resulting materials were characterized by x-ray diffraction and infrared spectroscopy. Both m...
